i notice i get plenty rich when spraying a 75 dry shot... But IM STILL FREAKIN PUZZLED!! I CANNOT GET THE CAR TO ACT UP ON THE STREET!!! only does the sputtering at the track???? i went out and made 3 passes today from idle up to a 45roll.. nada nada and nada on the weird feeling the car makes. But i can go the track, and it would do it on every pass from like 2 on.

Do you have a fuel pressure saftey switch? Maybe its not adjusted correctly.It looks like you can stand to go a little leaner on the 02`s,but that won`t cause the sputtering you talked about.

no FPSS on the car at all...

i even thought it may have been cause at the track i leave in 3rd and not D, but today i tried leaving it in 3rd and it still ran fine..

the only thing i didnt do was a little burnout like i do on the track
