well first this is my set up as of right nowrebuilt KAe stock spec internals-stock injecter-stock MAF-T04e garret turbo 60trim-duel n1 isis cat back-JGS turbo mani-Tial 34mm WG-emisson removel (everything except IAC)

is not a complete build but it is as of now and i do have more part to put in

here is the problem if i full thorttle it, the car wont pass 3000 rpm and start spiting fireballs like a bee R limiter

but if i go slow it will do that just fine it'll redline no prob

i doubt the maf will maxout just with this set up

I hope you have something to increase teh flow of the fuel injectors, or that is probably your problem, full throttle=boost, afr(on a wideband) should be in the 11:1 maybe a hair leaner.

Dude...quit screwing around before you blow your motor. It's probably already damaged. Do a compression test.

You can't just add boost to a car and expect it to work.

Well according to you its not installed.

I have 20 junkyard injectors from rx7's and dsm's, and a rx7 turbo. It doesn't mean my rb20 and ka24e are both turbo'd and making 600WHP.

Install your AEM and get it tuned before you blow your motor.
