What?
---- that, tell him to fix his ignorant ----. There is no way to tune that crap with the wiring quality varying in direct proportion to humidity, temperature, and vibration.

The few times I've seen that it's on a built 2.1 liter with a stock 60mm TB that can't support 230+ whp worth of engine. AFRs were controllable, however, so you need to suspect either multiple problems or something ------- wierd.
My only constructive comment: IABs opening?

Solved it, just a little unsure as to what exactly it was.
He had a 3" intake that went right behind his headlight, then it went to 2.5" to right behind his bumper lights.
I'm thinking there was some sort of restriction and the engine wasn't breathing enough up top. That, or 3" and that long piping is too much for a stock f22? I don't know, but problem solved and it's running like a healthy stock f22. lol
