Happy to be a new member and a first time Corvette owner. I just recently picked up my 2015 2LT w/ performance package Stingray and was messing around with the 0-60 timer. Tires warm, 8 speed auto, sport mode, traction on, Diablosport Intune programmed with the Diablo 93 octane aFe intake tune, aFe intake. My 0-60 run was 4.4 seconds. Am I doing something wrong or is it normal for an automatic?
