I would love to compare my bin file with someone else running a 383 SC 700R4 trans. I'm having idle surge problems (no vaccum leaks or TB Idle air adj issues) sine I bumped up my injectors to 30lbs. Also I would love to see how much timing you've taken out and at what rpms...ECM 165
I'm kicking out about 8 lbs of boost. Haven't dyno'd yet but hope to in the next week. Engine was built to 440 hp to flywheel before all the other goodies were installed. I suspect my rwhp will be between 450 to 500, maybe more:) It already runs like a bat out of %$#@. But it needs wband tuning on the dyno. I also plan to play with the timing too. This will give me an excellent chance to see if my engine combo is working as planned.
Yuour setup sounds impressive. My engine put out 440HP N/A also. I was hoping to get closer to 500HP before the supercharger, so that's why I haven't put it on yet.
I need to tune mine a little more first. What heads,cam and intake are you running? I have a wideband o2 and the Diacom scanner. If you ever want to hook up I live in Tracy CA which isn't too far from you.
