i am thinking that i had a tune already done on this car because it always hit hard and slammed in second, and third hard ok i bought a used sct tuner, he had a 2004 gt 5 speed, i have a 99 gt auto, of course i loaded his race tune and my car would not idle, set it back to stock then went into stradigy tune and made sure the 93 was selected and turned off my rear o2 and turned my fans on sooner ect. and there is leaning out option and shift pressures. but as soon as i load the tune and drive the car the shifts get lazy like a stock car, so if i have a tune already and im setting the pressures all the way up why is it shifting lazy? is it like resetting the trans? or is the stradigy tune based off the custom tunes for the previous owner? or when i load my stock tune should i just leave the pressures alone and see if it shifts hard again? an idea im having is that there is a tune already on my car so when i set my car to stock it just goes back to that, then i jack my setting up its just adding to the tune i already have and then not working right, i have not just left everything to see what it does, another idea im having is that when i go into stradigy its just based off the previous owners car, but then i thought if it was it wouldnt really run at all like when i loaded the custom tune??? im confused as to whats happening??
