Yes...at 3K+ RPMs, my pulls noticably better - it's obvious this is where the OEM plenum and TB were a restriction. With the 3.73s like mine, throw it from 4th to 3rd at about 40-45 MPH and she'll pull like a mother.
gears and some exaust and tuner are the only power mods you have right now. C&L with TB made a difference on my car. UD pulleys will be fine. You will feel more from the intake parts.
UCA and LCA, adjustable shocks / struts. don't forget the suspension.
