[Fox-4-Cobra]

It was a Dyno Jet, total timing was at 28, the AFR dropped slightly. I'am going to get a new MAM and TB and hope it frees up some power when it's retuned. I know full potential will not be achieved with the GT-40 Irons, cant afford new ones right now though.

Does anybody have an estimate on how lean it will get with a 73 mm MAM and an aftermarket 65 mm TB. Once I get those on I will not be able to get it tuned for several weeks.

Thanks For The Help!
