They are probably longer because you are making less power, so it takes longer to spin up the drum.Question please. I watched my pulls on the dyno and seem like they took so much longer than many others I have seen. ( Mustang Dyno) I have decent numbers @ 424 and 383 on 92 for basically bolt ons. Not sure if my intake is ported. Was on E85 but "detuned" due to track and location availability. I can't figure out the why my pulls are longer. I told him to give me a safe tune the whole way through the curve and don't lean me out just to show better numbers. Did my tuner put a different load on the dyno so he could look at things closer - kinda like a slow motion data so he could make more specific adjustments. It would be cool to see a dyno thread from independent tuners, not to disclose secrets but for the rational to reach a goal of a tune. - preferably track specific. My stuff is in my build thread. Sorry for the derail.
