Wow. I finally got my 03 Mach to these guys for 4:10 gears and a custom SCT chip with dyno tune. Wow, what a difference! The motor runs soooo much smoother and revs tons quicker. Should have done this a long time ago. I guess the combined benefit of the gears and the tune was alot more impressive than I thought it would. I'm pretty happy with the results of the dyno. With only an o'r h pipe and a 2 1/2" catback, I pulled 291 hp and 311 tq at the wheels. So....what do ya'll think? Decent #'s?
