Major Problem Rb25det

[Michaelove]

I've tried my local forums but no one can come up with an answer, so I thought i'd ask the pro's

Anyway! When I give my car full throttle, after about 4k RPM's it misses like CRAZY, I have absolutely no power then. But if I give it say, half throttle, I can reach redline much much easier, with slight missfire. I'm not sure if this it because of not enough fuel, no spark, boost leak or what. Maybe i'm hitting Rich and Retarded?

RB25DET

t3/t4 Turbo

10psi of boost

I need new spark plugs, so I'll also ask which spark plugs I should get.

Anyone have any similar problems? Any help is appriciated. Thanks!

my car doesn't missfire during idle or anything though. how do I tell if my coils are dead?

Hi.

Please do a search.

This is the most common problem when changing turbo and not installing come programmable management.

Thanks
