hey everyone . i was wondering what a sufficiant fuel system would be for the j tuners turbo kit . with the 5 psi spring . i was thinking just a carteck 2025 fmu would work f ine . my friend had s ome 310 cc injectors and a cartech fmu but for some reason it ran to rich and just wasn't running good . what are yall opinions?
Your friend needs to get an adjustable FPR so that he/she can turn down the base fuel pressure, otherwise the cylinders will be getting WAY too much fuel at idle and lower RPM.

btu can the computer run that big of injectors? i headrd it can only run 15% larger ... would stock fuel injectors be more sufficiant and reliable? well pretty much run better?
At 5 psi, larger injectors are not necessary, you can just use the BEGI unit to up fuel pressure (making the injectors flow more). However, with any more boost you're going to want bigger injectors, then you'll need the afpr to turn the pressure down when out of boost (making them seem smaller).
