help..turbo install threw engine code

i installed a revhard turbo on my 94 acura integra ls....i also rebuilt the motor(all new stock parts)....
i am getting code 43......which is "FUEL SUPPLY SYSTEM". The book says to check vacuum lines and fuel lines...so i did that and it didnt go away
could this be my stock fuel pump...i am currently running the msd inline fuel pump and vortech fmu......

What kind of boost are you running and did you buy upgraded injectors? A Vortec FMU without injectors is like pourting a gallon of water through a straw.

I run the Vortech FMU with stock injectors. It works just fine. The entire idea behind the Vortech 12:1 FMU is that it is to be used with stock injectors. If you had a way to control larger injectors, you would not need the FMU in the first place.
