driving the 240zt wich has a motor from an 83, it will be going down the road and anything past 3K will make a sound like the BOV is opening and staying open, but the other thing is, is that when under load, if i try and exceed 3-4k it will sputter and act like a rev limiter, so i cleaned the TPS and it ran a little better, but the sound of the massive boost leak remains..

 

Afm.........

 

wouldnt dought it, ive got a MAF setup ready to be put in, but i havent had the time do to the wiring fiasco in the dash...damn the SOB tried to wire it like a damn computer!
