Installed New Injectors Need help plz !

Post by ModMX3 - (Carmaster2005) »

Hello ppl I installed my 310 cc injectors today . I have NOT installed the turbo yet I noticed that when under full throttle it seems to misfire at 4,500 + RPM's im not sure if its misfiring or what bc it pulls strong untill high RPMs then it seems like its missing. Is this just because its running way rich ? I just never thought you could miss from running too rich. its not detanotion. If its just because its too rich I can easaly keep it under 4,500 rpms intill i put in the turbo. any help would be appresheated.

you are probably flooding out the engine unless you have some way to control fuel....if you dont I would take em out and put your OE ones back in.

OK I reverted back to stock injectors which i cleaned up, Runs better, I have a Vortex adjestable FMU thats hooked up right now. How much boost can you run with that ? how much will the stock injectors handle ? I used, high pressure fuel lines to hook it up with and clamps. I would like to run 12 Psi. would i have to upgrade my fuel pump ? thanks guys!

im assuming you using....220 cc now or 190cc? i dont know what car you have. Either way they wont handle 12psi, specially with an fmu.
