Boost troubles, but no black smoke - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I am having problems with an SR20det under boost. It just has a FMIC and full 3" exhaust. When under load (~5k or so) it acts like a fuel cut/rev limiter. I have searched, and yes, I have checked for boost leaks, Though I have not pressurized the system (yet). I checked every possible place and tightened anything that might have needed it.
I had a friend of mine drive behind me to see if I get black smoke when it starts to cut, and none appears. Any suggestions

does it happen at the same rpm every time or is it random as long as it is under boost?

Actually, it was the MAF, the wires were not connecting very well. I have to "giggle" the wires on the pigtail every once in a while, (until I get another pigtail)
