Dave, here is my dyno as discussed. Remember not to take into consideration the portion AFTER 6000RPM since the longer belt was slipping and the boost gauge was dropping considerably... It is also with a
stock header, test pipe and 2.25'' DC Catback. I'm still waiting for my kami... but at least I will be able to see if I will loose HP at low/medium RPM with it. Also the a/f isn't tune at all as it is not rich enough.
BTW, do you have the same J&S unit than PreludeSH157?
