Did you get the transmission tuned as well or just the PCM?

$8.5k 

PCM was sent to HP Tuners, they unlock it and send it back, then ProCharger sends the tune files and you load them through your pc. 
I shipped it on a Monday, arived to HP tuners on a Wednesday and they shipped it back on a Friday aternoon. 

 


Absolutely everything works. But the car will not start at the first press of the start engine (starts at the second press). You need to take if yo someone (dealer, mechanic, yourself) with an MDI2 tool and SPS suscription. I did it myself and I am not a mechanic. My local dealer sucks and was lost on what needed to be done. 

What exactly did you have to do with the mdI2? I just ordered a procharger myself. Was hoping the hp tune would be all I needed for the truck to work fine. I have no experience in using a mdI2 but very willing to learn. 
Also If day you added a cat back or cai to your truck can you change parameters with the hp tuner they sent with the kit? Thanks man.

Truck looks unreal btw

any dyno numbers? send some videos of idle and acceleration please. I had a Procharger P1SC on my 2001 Silverado 5.3 back in 2001 and I'm considering one for my 2020 Trailboss 6.2.....

Did you have your hood scoop painted or were you able to order already color matched?

 

Congrats on going boosted. It's a lot of fun. Ran 682hp at the wheels on my last mustang.

What tunes did you go with? 93 octane, E-85? You can usually pick up considerable more HP running E-85 provided the tuner has the ability.

I had the K&N Cai and just reverted back to the system that comes with the procharger. It took 7 tune attempts to get my truck correctly working but the guys from Procharger are good. I guess they now have the correct parameters for future trucks. I do not have any CEL on. 

 

The MDI2 I bought from amazon (a bit expensive). There is a Chinese version but I decided to go with the original one. You actually do not need one if your dealer has a clue about things... (not my case). It is only for the truck to start the engine on the 1st push of the button instead of doing it 2 times each time. If you need more details I will be happy to help.

I had it painted locally, just by giving the color code.

I live abroad, so locally I get 95 octane.

The scoop is just because I like the way it looks. It may be removed anytime. It installs with a strong double sided tape
 

the light bar is a must for these trucks. The original hi-low beam is very bad. 
I did install the switch on the right side, which I feel is much easier to reach while driving:

Can you share more info about the LED Bar?  Where did you get it? Wiring? Thanks

      Mangoal or FitcamX OEM Dashcam?

      By MANGOAL · Posted

      Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge.

      Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
