At Mustang week I dynoed my black 03 cobra with a Stegi Stage 3 ported eaton in it. I bought the car earlier this year, and when dynoed the car was leaning out.
The previous owner ran the car for 4 years with the stock 39lb injectors, and the stock fuel pumps, and even stock maf. The car runs very well, but is leaning out a little bit to about 12.5-12.6 Air/fuel at around 3600-4200 and again at 4700-5700 rpm.I just bought a mafia mass air chip ( haven't installed that yet) but Im curious to know if I need any fuel mods like injectors or a Boost a pump
The only other addition to that is a o/r x pipe and magnapack catback.
The car has10-12 lbs of boost on a 2.8 pulley. My only question is what type of fuel modifications should be done to the car?
It made 518 on the dyno, I kinda want to stay away from 60lb injectors and keep it somewhat fuel efficient lol. I do drive it daily during summer months
Is it possible that I can do 42lb injectors, and install the mafia and be all set?
