i am going to be stepping up to a 9# pulley. I dont want to use an fmu or fpr. After i get the pulley installed, i am going to get a chip burned too. Would 36# injectors be enough wihtout an fmu? i would go with 42's buy my maf doesnt go up that high (dont sell 42# calibration tubes for the 73mm c&l) and i cant really afford the new MAF. So will the 36's work or do i have to wait and get a new one for 42's. I dont plan on doing anything else to the engine really, so room to grow isnt really an issue either.
