HP Tuner files/tuning

[Wyatt Hurley]

I've been searching the internet for any publicly uploaded files for these trucks vs spending $1000 for a basic tune. I see that HP Tuners has a repository on their site, but no luck there. I have a 2017 L83 with long tubes, no cats, L86 throttle body/intake manifold, and DSX flex fuel sensor. I'm really just trying to get everything functional and operating correctly. So far I've deactivated DOD, turned off the o2 codes, turned on the flex fuel sensor. I don't believe I need to touch the transmission since I've had it rebuilt and tuned already. I'm new to this and trying to learn and do as much myself, so any advice or direction would be much appreciated.

HP Tuners only offers stock tunes on the repository now, so you'd never find anything there.

 

The problem really comes down to the fact that every vehicle is different using someone else's tune can often cause problems if you don't know exactly what is being changed.

 

HP Tuner forum does have a lot of good help and may on there will help for free. The key is posting everything about the vehicle, the tune file and logs of the vehicle running. If you can explain what you're trying to do and what might be giving you problems, that's the best way to get help.

 

Changing the throttle tables is more involved than most people think. Just read this thread.
