what could be causing it, as it moves with the brake off it is like it is hunting surging?? I did the 383 and will have the pcmforless computer in it soon. Think the O2 sensors are bad? Put a new map in it and cleaned the MAF screen and wires with contact cleaner per PCMforless. What do you guys think?

also I put 30 accel injectors in it.

I would wait for the tuning and then see what happens. Tuning may clear up a lot of your problems.

???? Also I had the new pcm set up and asked if the cat could be gutted and he said yes it could, should I do it, cause I smell rotton egg smell like the cat is working bigtime, motor runs hot sitting still like it cant get the exhaust out fast enough.
