need help with fuel system
since i want to hit 10+psi on my 4.3L i need some help with understanding the fuel system. im gonna go with 2x extra injectors.
if i go extra injectors do i need an FMU ? i know if i run an FMU i can run 7 to 8 psi on the stock fuel system. so for the extra injector controller should i just put it on a msd boost switch to kick on @ 7 or 8 psi? how should i go about adding the extra fuel with the extra injectors btw i cannot upgrade my stock injectors because they are poppet style. so im stuck with the stock 19lbs'ers. thanks for the help thanks |

Re: need help with fuel system
im running three on my charge pipe near throttle body. one is set at 3 next is 6 and next is 9. start off one going off at 1 lb. and if it bogs move up to 2lb or 3lb's and so on until it pulls nicely and their is no bog.
