If ecutek has ability to control the timing better and actually able to make the timing advance to a point where you can hear the detonation, i would not be surprised to see at least 10~15hp gain throughout the band.

give you a tip for uprev guys.. if you want to tune an NA 370Z engine, just put crazy amount of timing advance (burn time table), it will only run up to where it allows and that is all you will get. no need to spend hours on dyno hoping to leech more out by fine tuning it.. until uprev figures out how to advance to a point where it will knock.

ecutek seems pretty promising and seems to get more popular.. i dont think we have a tuner in nz, and ecutek wont let users touch their ecu's, only by paid tuners, this is the only reason why i am still with uprev
