Yes I feel a difference more torque.Better idle. My mods are 3.73,steeda tune ,steeda cold air,steeda pullies,and I ordered the trickflow intake and 70mm TB. flowmaster 40's.03 GT
Also for 650 dollars I think the tune is worth it from a driveability stand point.And its CARB certified for testing when my car is up fot it. Steeda is expensive but Ive been dealing with them since 96. My 96 GT was supercharged and a automatic and the car ran a 12.9 with a stock driveline and stage 3 suspenion.Im happy with them.
