I need some help. I got JLT CAI, Steeda UDPs, O/R H-pipe, built tranny w/ short throw(hittin gears not the problem), and the Xcal3 custom tune on 746. I thought I had plenty of power to do it, but I just lost to an '03 Mach 1 which is stock except for no cats. I understand the 3.55s and the DOHC, but I shoulda still had him. He got me by a car length. What could be wrong? What do you guys think?
