Over a year.
Drive it every day, race it, and beat on it constantly.

Nasty, any supporting mods? Like beefed up splines in the rear axle, built driveshaft, supporting mods for the SC like catch can, ect.... All the small stuff that adds up. Do you have a list of that?
I ask cause I, like you, daily drive my stang.

What if we're only running 8lbs of boost on a m90? Would we even need a BAP?
Would the stock fuel pump be suffice? Would upgraded injectors be needed?

IMHO yes you would need the BAP, but the GT500 dual pumps are better, and yes you would need the 39# injectors. Also you would need a different tune. If you tinker with the kit at all, you will need a new tune.
