racer rx

I installed a Nipondenso pump earlier this year.

What should my next upgrade be? Injectors or RRPFR?

I want to run about 15 - 16 psi of boost.

What should i do to increase my margin of safety?

thanks

If you are going to run 15-16psi you need to upgrade your injectors. It is hard to come to any sort of conclusion without your mods stated but you will definately need injectors for that boost range.

you are gonna need a intercooler if your gonna run that much boost as well as some kinda ecu modification.

the power really tapers off after about 14psi.

Hey Shunks what do you mean power tapers off about 14 psi?

you should upgrade your injectiors, dont know if the pettit will do it though. I think that the only way you might be able to do it with the pettit is to upgrade both sets of injectors but keep the size ratio the same and what not, other than that, power fc.
