I had a discussion with Mike about some stuff prior to him getting it.
Personally, I wish it wasnt there or a person could choose to turn it off, but GM doesnt ask my opinion.
A guy could have it "tuned", but just have it turned off. It will void the powertrain warranty however as any time I go inside, I have to get all the programming data out of them and cross it to the GM system to verify its legit.
If a guy is going from an older truck to one with it, he will notice it for sure, but on the new ones it actually happens so seamlessly that even I have to pay attention most times to notice it.
