Hi all, I recently completed a series of mods on 05 GT (Steeda CAI and under drive pulley's) that resulted in a very respectable 297rwhp and 297lbft of torque following a SCT Xcalibrator 2 custom tune at Tapp Auto here in Ottawa. Now I am thinking blower to take my baby to the next stage. I am intrigued by the benefits of a twin screw design (more consistent power at lower revs etc) and Whipple say they will have a kit out soon for the 05's. Are there any opinions pro or con on that technology? From what I've seen so far (and what my tuner recommends) the Procharger seems the way to go. Comments, ideas and rants welcome. Cheers!
