So I recently had some mods done and thought I would share the results.

 

BTR 220

Kooks headers/green cats

E85 Sensor

Magnaflow catback

 

I wont even bother posting a sound clip; the magnaflow literally makes it quieter then stock (engine noise is way up). I could hardly believe it, because when I ran long tubes and corsa sport it was insanely loud. Stupid loud..

 

I should mention that I have 33" 10 ply LT tires that weigh roughly 70 pounds each. Which is why the numbers are low. Truck was dynoed with e40-e50; with 93 it only made 10-15 less hp. I was told it was dynoed in 5th. Not sure how that works though, as my my tires are only rated for 112...

 

Overall I'm quite pleased; gained roughly 100 hp/ 100 ft/lbs at 5500 and gobs more up to 6500 (which the truck now shifts at)

That’s awesome! Great numbers for a cam swap. 
 

So you didn’t put that crazy intake on?

 

What lifters and rods did they put in?

 

How does it pull off the line? Up top?

No I decided to not put the msd on. Davenport didn’t think it would make any extra power.

 

They put in GM performance lifters, and btr chromoly rods.

 

The truck feels pretty good down low, better actually. Pulls strong up top too.

 

Hey, what oil are using? Davenport put in driven di40 and I don’t know if I have to stick with this oil, or if I can use something else. 
 

driven di40 is a racing oil and is only good for 5-7000 kms.

Just put in any 0W40 or 5W40 oil, it's going to be just fine.

 

It's just a camshaft swap, it doesn't need specific racing oil.

I use Amsoil 5w30 Signature series and Amsoil filter. Strange how they told you to use that race stuff

They Just got back to me, looks like I can use any 5w40.

 

Im thinking Pennzoil, but it doesn’t specify a drain interval like it does with the dexos rated oil…

Here’s another dyno showing the difference between 93 and e45. Not a huge difference but the truck feels way quicker using e85..

Was dynoed in 4th

 

Regretting I didn’t do the intake manifold. Looking at getting btrs truck intake now. Doing a gear swap, and potentially the drive shaft

      AFM Experience

      By Grumpy Bear · Posted

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
