Ok i have a b18c5 with a ls stroke 84mm bore.
ok the issue is:
from a dig or roll when full throttle from 1st to 2nd, when i hit second the car does a complete nose dive, RPM's drops to 0 for a sec or so then it comes bac and stumbles through out the rest of the RPM. it also does it from 2nd to 3rd or 3rd to 4th.
the b18c with the sc61 base was used and change the injectors size to 880's. the car idles real good its just the one problem.
its also running on a f.a.s.t 3bar on 10lbs
