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.
