-Greddy VSPL intercooler
-3" Exhaust
-Power FC
-SARD 550cc injectors
-walbro 255hp pump

pretty basic setup. going to tune for higher boost later on on some race gas just for fun.
This was with 20 pounds on 71R? I made around 320hp and 309 with 17-18 pounds on the disco on my 240. Hmmm what would be the main difference in our power output? I had 264 cams but that shouldn't make up for that much. And I had an RSPL fmic but other than that we had the same setup.

From what you're saying you had creep pretty bad though. Good luck with the head gasket.
