Well finally got the sr20 out of the shop and it runs really strong but when I let out on the gas the car tends to lung a bit or gets kind of jumpy but when you ease back into the gas its fine... Any ideas? I was thinking Compressor Surge or Vacum leak...

The car under gas runs great though and spools fine.

Try replacing your fuel filter.

It's on the shock tower by the intake manifold.

My car lunges also. Tuning the bov helped alot. My bov was releasing too soon, so tightening it helped smooth out power delivery. I'm also running an auto 63 ecu, which I hear causes lunging. I just bought a 62 ecu, so I'll see if it helps any.

Thanks man. My friend thougt it maybe the BOV also... Ill check the BOV first to see when its releasing then ill go to fuel pump. I know my ECU is the same one that came with the engine so thats not my problem that I know of.

Recirculating the BOV helps, if you're blowing off to atmosphere.
