Ok I got my car on the road today driving it around town gettin use to it... Wow!!! I love how fast it accelerates i pulled cleanly away from a wrx. My car would buck around 5500rpm up. I have a full exhaust n just a cone filter a fcd and a safcII. we figured since the safc is untuned n stock fuel map we would see if giving it more fuel would help so we gave it 5% from 4600 to 6000. It helped but didnt cure it. We went to 10%, pulls strong in 1st to redline no stutter/bucking but in 2nd i have a lil stutter n 3rd i have a stutter. So I believe tommorrow morning ill change it to 15% and it should be fine. Just wanted to let you guys know how I fixed the problem and all along I thought it was my wastegate...
