well i installed the pulse monitor and downloaded the new comp tune on the website 6-6-08 and my free rev sputter has gone away completely.... still does it a little bit on the street but i am way happier:rockwoot: i will try some of the other tunes later this week....
im also gonna try to get it on the dyno again as i laid my 590 with the bad sputtering problem.... but that probably wont be for a month or more:bang
