Hello everyone!

This thread will serve as my personal build & service log and allow others to follow along.

I just got myself a dream of a truck, a 2017 Summit White Sierra 1500 5.3L SLT CC SB 4x4! This is my first GMC and my first brand new vehicle I have ever owned.
Package options: SLT CC Premium Package, Power Sunroof, Full Feature Front Bucket Seats/Center Console, Intellilink 8" Touch Premium Audio w/ Nav, Trailer Brake Controller, and an optional 3.42 gear ratio.

 

post-171329-0-29824900-1491631581_thumb.jpg

While it is still very new, I already have some modifications planned out!
Tint, Air Intake, Cat-Back Exhaust, 2.5" level, 33" Toyo MT rubber, Console Vault, some customized LED lighting, and a DiabLew custom tune are all on the list.
As always, I'm sure the future holds some more.

 

First the tinting to keep out the heat/uv and provide a clean look. This time around I will be stepping up the tint game by going with Suntek CXP which is a Non-Metal, Nano-Hybrid, Carbon Construction tint. Excellent for beating the heat, infrared, and UV rays with impressive Total Solar Energy Rejection (TSER) ratings compared to the competition, it also comes with lifetime mfg warranty including fade. It should be noted that it does not interfere with any electronic signals like some metallic based tints.
Suntek CXP 80 will be going on the full windshield, the sunroof, and the factory rear three windows while providing 44% TSER but with almost no color shade at 80% VLT.

Suntek CXP 35 which has 53 TSER and a 33% VLT will be applied to front driver & passenger to match the factory rear three window's color shade while providing the heat refraction advantages.
With a white truck and full heat protection on the windows all around, I will be very much looking forward to testing the setup this summer as local temps can reach 118 during the summer. One of the reasons I did NOT pick a black color vehicle. :)
I already have the appointment made so this should be something you all can take a peek at relatively soon!

 

Moving onto the performance based mods I intend to install an air intake system, a cat-back exhaust, and possibly a custom tune.
The air intake system I chose to go with is the Airaid Jr. which for around $200 provided the biggest bang for the buck and was recommended across many forums.
This includes an intake tube to replace the horribly choked up stock intake box and a SynthaMax Dry filter.
Typically users report 8-12hp gain and sometimes up to 2MPG improvements over stock.
While there may be some fancier options available such as CAI or AFE Power they don't seem to yield any additional benefits besides looking pretty and that alone won't convince me to part with my hard earned clams.

 

To be continued...

Continued from Part 1...

I chose the Corsa 14873 cat-back exhaust system after spending alot of time reviewing sound samples through youtube videos.
I particularly like the sound of its bark upon cold start up and the moderate sound it produces during real world driving (low to mid range). When really stomped on it produces a very loud note with raspy attitude behind it.
I ultimately chose the Corsa over the Borla S type because I dont prefer the lower deep smooth tone of the Borla, because to me the Corsa has more of a character to its sound.
Its ordered and should arrive in around 8 days!

I intend to get a Diablo Sport intune i2 with a custom DiabLew tune.
There are many satisfied customers of Lew and I feel confident that a proper custom tune will pair nicely with the intake and exhaust to produce a healthy and fun performance package.
Also since I want to run larger spec tires I will want to adjust the speedometer to be accurate and the tuner will allow that.
That wraps up my current plans for performance.

As for my lift/level plans the Rough Country 2.5" lift/level kit is ordered and should be here within a day or two.
This is a widely respected kit and should allow me to run 33" tires with minimal rubbing against the sway bar at full lock.
I had my eyes on the Toyo 33" Open Country MT's but have been advised against it by a few tire shops due to the extreme local summer heat citing very short tire life.
Another set of rubber that has my eye is the Nitto Trail Grappler in 295/55/20 trim, similar appearance but All Terrain based and should last much longer.

Lastly I want to add a Console Vault, essentially a 12g safe with combo lock that bolts to the frame inside of our giant center consoles.
Its great to have a safe place to store valuables.

I installed the Corsa Sport 14873 yesterday.

I placed two cuts of 4x4 wood on top of my jack and then lifted the truck from right in front of the right rear tire where the frame drops down towards the ground and then supported with jack stands.
Was able to get full suspension droop this way and I was able to remove the stock exhaust in one piece.

Its a tight fit but with two people and going slow and surely you can manage by rotating the muffler about 120 degrees when it reaches the rear axle and then continue sliding it out the rear.

The new Corsa went in easily, I supported the muffler with some jack stands and a towel to stop any scratching. Started at front and worked back.
Took me about 2 hours to remove old and install new and finalize the angles and torque.

Started up and was extremely pleased. Very nice V8 bark upon cold start, settles down into nice rumble as it warms up.
Perfect amount of volume and great attitude/tone with regular driving. Step on it and it becomes an animal.
I would highly recommend to others and I will post a video soon.

 

Late last week I got the tint put on, I think it came out fantastic!

Ended up going with Suntek 70 on windshield as the installer recommended because it had 10% better TSER and was only a hint darker.
Suntek 50 went on the rear three and sunroof, and Suntek 20 on the front two sides. I went with this because the lighter 30 and 40 seemed more blue hued rather than black and I wanted to match the overall shade of the rear three.

I believe I got damn close, and from the inside its still very easy to see out and you have to look hard to notice a difference between front and back.

I think it looks fantastic with stock suspension setup.
Hoping it looks as great after the Rough Country 2.5" level/lift tomorrow!

Decided to keep the suspension as is.
I just love the current look too much and also while I have been considering a Bakflip MX4 bed cover I read about water leaks due to the leveling of the truck preventing the drainage channels from working properly.
I'm going to allocate the funds I had earmarked for level kit and installation towards the MX4.

Here's another shot of the 275/60/20 BFG KO2's on OEM 20" Polished rims w/ stock suspension.

Do you mind sharing how much rake you have. What does your front and back measure. I have same truck, same wheels and looking to do 2” level with 275/60s on those stock rims, but after seeing yours...I think it looks good with those tires. I am on the fence bc of possibly making the truck squat or nose high when towing. 

I appreciate any feedback and thanks for your time. 

Your truck is lookin good!

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
