Sct tune help.
My buddies got an 02 v6 5speed. He recently bought a tuner for it, and got a "custom" tune for his car. His mods are small, a cai, catback, and 3.73's. Well he put the tune on and said it felt slower. I didn't believe him. But he dyno'd his car and with the sct tune it made 154, with a different sct tune it made 156, and with a completely stock tune he made 161! Isn't this 300 dollar tuner saposed to give him more power? What is he doing wrong? He got his tune through his email from sct, put it on the tuner, then put it on the car. So what's he doing wrong?
