you cant go anymore unless you add meth to the mix...remember you maxed out the fuel pump...we will throw a 22-25 pill in the nozzle and leave it at that, i dont want you blowing the motor but i know th truck will cut a way better 60' and thats all the help you need, i say by looking at the dyno chart we spray from 2500-4800 and let it go off that!
