I have a 2002 Z28 with a T-rex cam, pacesetter longtubes, true duals w/ x pipe and 18 inch sweet thunder mufflers. i had dynoed at 416.71 rwhp and 379.45 rwtq, my question is how do i go about increasing my torque numbers? keep in mind that these dyno runs were through a stock TB with a stock paper filter and whisper lid...
