Who has a prelude with stock 310cc injectors running boost? Whats the max PSI on the Fuel pressure that will produce the max HP/BOOST safety level. I hit 10 psi tonight after I took the 1000cc RC injectors and went back to the stock ECU cause I cant afford the RACE fuel that it was tuned for. I'm currently at 55psi on the fuel and hit 10lbs open wategate but when I left off the peddle the ---- hit 17:1 AFR. PLEASSSSE HOOK ME UP

So...you let off the gas and only hit 17:1 AFR? Should be more like 21:1...You never heard of fuel cut on decel?

Yeah I know what you mean but now that it's back to the stock ECU when I go to start it the wide band reads lean after it heats up and it acts like the IAC is causing the revs to bounce, so I unplugged it and it went to 11:1. I disconnected the FPR and put the O.E. one back on and still no change. Guess I'm going to have to go back to the original setup and go back to the dyno and detune it or just wait a deal on some racefuel that I cant pass up. $7.29 a gallon is what the CAM2 fuel is costing here in Southern Indiana

Yea just leave everything how it was and retune for pump gas at, I'm guessing a lower boost level. Itll be ok

I hope you're not running on the FRM sleeves.

HELL NO THIS IS A FULLY BUILT BEAST, Ross 88mm 9:1 comp, Eagle H beams, OEM bearings, custom eversized oil squirter lines, LA PERFORMER Sleeves, Ferrera Stainless Valves, Skunk2 dual valves springs with titanium retainers, Type S cams, cut valve seats. ported intake with a 60 frit finish, and a ported exhaust with a polish finish, RC 1000cc injectors tuned to 578hp now taken out and back to the stock 310cc and heading back to the dyno to run on stock wastegate 6 psi pressure cause of gas prices.

Why not just tune to get the most out of pump gas? 6psi on that setup is a waste of time
