Hey All,
Excited to get back in to the season in a month or so and planning some additional mods. I'm currently running a Procharger Stage 2 P1SC kit on my 2015 with a 4.63 pulley (still only getting around 7psi boost) and looking to add some boost. I was having quite a few issues with the tune last season (false knock, high gear load drop). Got to the bottom of most of the false knock, though now going to up boost a bit and get it on a dyno for tuning to get it dialed in.
Anyway know what the smallest size pulley I should be looking at for use with the stock fuel system, Boost A Bump and 52# injectors would be (also stock internals, drive shaft, etc.)? If I go with a larger injector to try to get to around 11psi out of the Procharger, would I be OK on the stock fuel system + BAP? If I get it to 10psi, will I still be OK with the MU52's? I spoke with Procharger and they said that I am OK to spin the P1 at 11psi, but wouldn't recommend any more. I'm only getting about 530whp on a Mustang Dyno out of the kit right now and load dropping off in the higher RPM is still an issue in 3rd/4th. It's Lund tuned and though they've been responsive in trying to help with issues, it's certainly been a painstaking process. I've seen people at the 650whp+ mark on stock internals, but would rather be safe than sorry. Hoping to up boost a bit and get this thing on the rollers in April and get it running smoother and with more power.
