There is no way the car would pull "440ish and 375ish on a dynojet." That torque #, btw.. is close to stock. Mine made 389 HP 380 torque on a dynojet stock.
Maybe I'm misinformed.. but is that even possible? 412 seems more like it.. maybe.. maybe approaches 420.. but that would be a whole lot of gain. A 2012 GT 500 makes about 440 -+ on a dyno, btw.
