Are you really running E0 pump fuel or are you running the standard E10 that is offered at pretty much every pump running 87,89,91 octane?
Change the stoich to 14.2 if E10 and reset the trims.
Past that I don't see a "huge" problem with the trims. Sure they are more positive at time but I've seen stock calibration that were worse. You can take the time to dial the fueling back in to get them closer to zero if you want.
Clean the MAF if you haven't yet too, do a tune up if it's never been done.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Okay so new problem, Flashed it back to stock and now I get the error of "Unlicensed vehicle" When I have definitely bought the credits for the tune file and the ecu multiple times. I have tried resetting the ECU and the laptop. No Dice.
HPtuners doesn't treat their customers very well. This has happened to me before, it just wouldnt re-flash again without more credits for no reason.
Can someone help?
