I am not opposed to getting a tune but I do not want to void the warranty so I am patiently waiting for GM to step up.
This car was bought primarily for my wife so I am only in it a couple times a week when she needs the Tahoe.
With that being said she is not unhappy with the performance and really don't care about the 0-60 times. She is just ecstatic she has her RJT Camaro. I am a little confused about that because her stock 97 Z28 pulled harder off the line and she doesn't seem to notice that. Probably because I am the only one that put that car through it paces. I could smoke the tires on that car at will with T/C turned off. She hates it when she is in the car with me because technically it is hers and she doesn't care for me driving it hard.
Anyway there is a tune company offering a tune that is "undetectable" so I might look more into that in the coming months if GM doesn't step up and re-tune our cars to get stated performance.
