So is it 100% true that the diablo flash tuner does not void the warranty on the powertrain?
Based on my research, and talking to a couple check mechanics they said Tech II tool the dealership used can detect that the stock tune was changed at some point, even with the "flash technology".
So this must be a complete different process that something like EFI Live or HP Tuners...
Do vendors have any type of guarantee about not voiding the warranty?
I can not stand the AFM making the car bog between 45-55 so bad with the A6, and even seems like it will bog on the interstate and vibrate. I told the dealership I have to either turn it off, or have them order and warranty M6 gears to pick it up a couple 100 RPM hoping it would help.
