Have the KPM 1000hp fuel module, KPM 1000cc injectors, KPM reg, went together super easy, anyone could do it, its set and forget really, Made nearly 500rwhp on 98 and 18psi - looking to step up soon with bigger turbo and e85 and except it may need bigger injectors but will handle it fine. Takes care of the fuel pressure without needing to go after market rails or regs, keep engine bay looking standard, couldnt be happier unless it was cheaper/free. The supplied data with the injectors means it takes only moments to get it idling and running sweet.
