once you restore the original backup stock tunes to the vehicle, the dealer can't tell anything....

Not to be a dick, however a foot print will still exist. Unfortunately anything short of swapping PCMs will result in the dealer finding said footprint if they look hard enough. It's similar to the idea that even if you erase a hard drive the files can be recovered. Also does hptuners support these trucks already? I believe a guy in Houston who is also a site supporter posted 1/4 mile times for his 2014 tune. (Goes to find thread) just trying to figure out if I am way off base. I will edit this post if I am wrong.

What footprint are you referring to exactly?

We have done our homework on this. We have confirmed time and again that we do not alter/change/edit anything to do with the CVNs, which is what GM advises dealer techs to look at to determine if a vehicle has been tuned.

We leave no trace of having been there

Where did you see that?
Gains are indeed the same on both tools

We moved AFR around during testing. Just because it may not mind being leaner does not necessarily mean it will make more power there

We also offer custom tuning, and the end user can adjust the WOT AFR if they want to lean on it a bit more.
Remember, these tunes are designed to be safe across the board, and the gains are solid while still leaving some room for safety on the table.

Thanks

Notice the HP/TQ numbers different between the 2, this is why I asked I figured it was inaccurate.

This is really encouraging... I'm honestly surprised how fast it happened.

Congrats guys!

GDI engines tend run an average of a point leaner than port injection. In all of the ones I have personally calibrated, even under 22+psi the average afr is 12.16-12.8 on gasoline. Running high 11's low 12's on a gdi setup is going to cause an injection timing issue and possible misfires. At least in my findings.
