i have searched the internet over and over again and can not find anyone with even a similar problem as i am having. my car is running insanely rich and misfiring at idle w/b is reading 9.4-10.1 i have replaced the ecu,injectors,maf, ive done it all trying to lean it out and with no result ive even put several sets of number 7 ngk r plugs gaped to between .25-.32 we've tried both
mod list:
cx racing turbo kit
.50ar to4e top mount
walbro 255
tomei fpr (set any where from 43.5 all the way to 0 psi no change)
stock ecu
stock maf
stock injectors

i have a nissan master tech helping me
the fact that i have stock ecu,maf,and injectors should not effect how the car idles there is a hidden problem here the car has a extremely rough idle like that of a built rotary. dont want to be rude but i dont need to be preached to about how i need to learn about what im doing everybody has to start somewhere

It could be a faulty fuel pressure regulator or leaking injector(s).

Did you do a compression test before reposting this problem?

Again sounds like you have several issues. The bone stock KADE ecu and injectors were not designed for boost...

My reply from your other thread still stands. I would again suggest hitting up Amazon for some books on turbo/supercharging an engine so that you can gain basic knowledge on the principles involved... I hope for you that the engine is not already ruined at this time...

Good luck!

This. The diaphram in the FPR might be leaking and causing it to simulate a medium to high load situation.

swap the stock one back on there and see if that helps.
