i have a 94 vtec, built top to bottom with a fmax turbo kit. im only running 10 pounds of boost since thats the factory setting on the supplied mf2. i put in a wahlbro fuel pump, aem rail and regulator and have 550 rc injectors but i havent put them in yet. my question is, can i put the 550s in and just lower the fuel pressure or do i need to get a fuel controller? ultimatley i would like to ditch the mf2 and secondary injectors. tuning the mf2 is hard to do and i cant afford stand alone right now. building the motor really cleaned me out
any tips? let me know

anybody? help a brotha out!

 

i dont see why you couldnt put the 550cc's in now, should be fine.

but i would reccomend ditching the mf2 and getting some real fuel management when u can afford it of course :drunk:

 

you'll need a fuel injector controller. the stock ECU wont be able to handle the 550's, resulting in the motor dying at idle, or at the very least, idle shake and die when you step on the gas.

 

wich would be a better controller for me? safc or vafc?
