just some advice, your injectors are maxed most likely, you won't be able to control fuel very well, and 13.3 on a dynojet is too lean for the street/strip. IMHO. and you need EFIlive or ease scanner to monitor IPW and DC. I would say this hurting you slightly performance wise, but great for dyno numbers.
