I have a 1972 GTO that has a 2006 GTO 6.0 in it with the 4l60e the issue I am having is it has this valet mode in it where you have to turn the ignition on then shut it off then start the car if you don't do that car has very little power I have ordered my hp tuner just wondering if anybody has ran into this and if so where will I look when I get my tuner up and running thanks
