Fuel pump

[mitch1659]

I have intstalled intercooler piping, BOV,intake, plugs 8.5 wires, and a cat-back exhaust. Havent touched the boost at all but for some reason i spike up to 15psi when i get on it and as soo as i do that it bucks. I believe i need a fuel pump just not sure what to get and if i need the get injectors and a regulator. And could the boost spiking be a crossed vacuam line? If i could get some help on what i should do or what the problem is please let me know.

Thanks,
Ryan

I the greddy BOV and a boost gauge. Before getting the fuel controller, the injectors and the regulator is it possible to just get a fuel pump?

If so how what kind and how big do you recommend getting?

If you have a MBC (I guess you don't, though) how do you have it hooked up? Is it T'd into the BOV line or is it between the compressor outlet and the wastegate actuator nipple?

If you do not have a boost controller, one of the vacuum lines hooked up to the BCS may be leaking/torn, causing your spike.

Before you get injectors and a regulator, you need boost control, BOV, boost gauge, and fuel control (such as a S-AFC, but you can get that at the same time as the injectors).
