I do know that MM&FF had problems on their mach 1 when they installed the screen the wrong way. They lost something like 7 hp, from just putting it in upside down or sideways. They did gain power with it out but were concerned with it leaning out.
Fear your car made 457 rwhp with just a catback, tune and 2.93 pulley thats bad ass man how much boost are you seeing and how conservative is your tune. Thats the exact number I wanna see out of my cobra.

Thanks man....Rick@Amazon almost nailed the tune dead-on on the first try. It was alittle Lean in the midrange I thought. Up top it was @11.8-11.9:1.Im waiting on Rick for opinions. I dont know how much boost yet I havent got a gauge hooked up yet.
