i just got a twinscrew saleen supercharger put on my 2000 gt and i got it tuned but i feel no difference in the car it feels the same as before also there is no whine i'm a little confused on what to look at

 

The only thing that springs to mind is the bypass valve might be stuck in the open position, not allowing it to close when engine vacuum drops, which would interfere with the blower building pressure.

You tuner should have seen something like that in about ten seconds though. Did the numbers on the dyno look ok? Maybe the valve jammed open after the tuning session?

 

Are you flooring it? I have a series II and it only whines when you at WOT. You will not hear it during normal driving. Should feel a little more power though when not WOT. Take it back to your tuner.

 

Are you seeing boost on your gauge?
Agreed with the other comments, I only hear my M112 when I really get on it.

 

I found the problem I just realized it has a underdrive pully so it's barely Making any boost thanks for the help guys

 

Was the underdrive added after the car was tuned? When you say you "got it tuned" was it actually at a shop with a dyno or were you talking a canned email tune? A shop should have picked up on the blower not making proper pressure.
