the stage 1 map was ok, but its the stage 2 were the delievery became quite on/off, like it had a few power bands. I never really noticed it that much until i started having goes in other ones, and then it became very obvious, like i say though, this was a couple years back, they have prob changed it now.
although a guy on brisky timmyboy had stage 2 with identical characteristics to me, got it on JKMs rollers and made 250Hp and 270Ibft which is low for stage 2 anyways, he then had his fuel pump fitted the stage 2+ map installed and made..... 250.3 or something like that, mine made more than that, although it was on AMDs rollers which back then used to read very high.
