Thanks for the reply... I am going to be installing a Vararam intake and Borla catback exhaust regardless. Reason I was asking about the tune is because Vararam makes both, tune and tune-less intakes, and I was curious as to which I should get. If I'm going to be putting both exhaust and intake in the car, might as well go for the tune too?
For legal purposes, I have to advise don't touch your car if you are worried about warranty issues.
The Fact is there are no GM approved modifications available, and it is the call of your Service manager, so this is a discussion best left between you and him.
I don't think anyone is going to come knocking on your door and ask to see your computer LOL.
There is Nothing in the tuning that can hurt your car so I really don't think you have anything to worry about, diablo lets you return to stock any time you like.
I have no solid release date for Intune.
From what I hear it will do exactly the same thing as the Predator but reduce inventory of part numbers like the Trinity, one part number for all vehicles supported by Diablosport.
Sorry if this is not what you wanted to hear, I have to tell it like it is.
