which one will work better??? i have dsm 440 cc injectors ??ishould i hack the vafc with the injectors and not use the fmu. i was told that it was not a good ideal to use all three in this set up??new fuel pump or the dtock on with the vafc or the fmu????

 

I would say your best bet is to ditch the FMU and run the AFC hack with the DSM injectors. It is only good for about 10psi, but it's a good start. An upgraded fuel pump is a good idea, but not necessary for this set up. If you decide to upgrade, go with a Walbro 255lph.

 

You can do either.
I personally ran the fmu,sfc,and 310cc injectors to get my numbers. It worked good for me.
Which ever you decide they both work.

 

Personaly I am running a FMU, and VAFC with 440cc RC injectors
works for me

 

sounds good i'll try it out and see what works out the best.
thanks for the infor.
