So I'm finally driving my swap ... rebuilt 3sgte with gt28 turbo.. it runs great.. however I have an issue when I come into boost.. typically around 6-9psi.. the engine will stutter and if I keep the peddle down it will clear up..
Any thoughts on this? I know it's kind of a vague description but that is pretty much what happens.. just stutters.. and I know it's not fuel cut cuz I don't see the CEL flash and I'm not anywhere near fuel cut pressure. I'm thinking that it's either 1. ign. timing 2. throttle position sensor (needs to be adjusted) Other than that it pulls well... -------------------- 87 4runner DLX 22re, 5spd, 4.30gr, 4" lift, 30" tires, HID w/ Projectors, 6spkr + sub, custom exhaust, 94 celica leather seats, SR5 gauge cluster and clinometer. Future engine swap... possibly a 2jzge.

Well I'm gonna pull the ign. timing back a smidge and see if that clears it up or not. I'll post tomorrow with the results. I gotta make that knock led.
