i don't know what it is.

When i floor it, i'll get less power. 3quaters throttle i get more power.
But my power kicks in twice, as if it stays at 180HP then jumps to like 200.
its like the powers not even there.

help?

thanks.

Have you changed your fuel pump after swapping in the SR? Check your fuel filter also. The 300zx TT works really well.

Possibly a small boost leak? Maybe your piping holds at 4-5 psi but pops open at 8?
