FP RED setups, recommendations, and advice
if you look in the dyno section on the forum most guys cant get past 460 with a single pump. That is why I said those numbers. If you got 550 on a mustang dyno its probably calibrated with a funky weather correction. Im just going by what im seeing. theres nothing special about your particular 4g63 thats going to allow you an extra 100WHP on the single pump.
