lag when revved?

Your TPS sensor may be faulty. Even if it's new, it may still be bad. The other thing that you can try (if you haven't already) is elongating the holes in the sensor so that you have more adjustment.
 
Don't screw with the TPS..set it anywhere from .85v to .98v and be done with it. I the idea of gaining performance from playing with the TPS is a pipe dream, and anything over 1.0v is going to cause issues.
