If it was leaned out in the midrange, it would act civil, make more power and get better mileage and be closer to emissions targets.

My car does make 422 whp at 7,500 rpm. That part is ok. I'm not suggesting they lean it out at redline. It's under 5,000 rpm where the tweaking with Stillen's tuning needs to occur. If you look at their press release, they are getting 340 lb/ft or torque in the midrange, where my car is only making 280 lb/ft.
