What's your trap speed?

I think you should free up your exhaust and get cold air intakes. HFC's, a catback, Stillen G3's and a tune. Even if you get high flow cats and an aftermarket y-pipe, that will help greatly.

If you're running high 13's without the nitrous... That's about right for a basically stock Z. The short tails aren't going to free up that much power and the K&N intakes are most likely heat soaking.

If you still have your system in the back, too... I'm not sure how much it all weights, but seems like it might be quite a bit. That's creating a lot of extra weight your Z is dragging around.
