ok i tried to set my levels sort of the same as some of the other guys, but it still not right. its like........... when you put your foot flat it will spool till 4000rpm then a massive cut in everything. hard to explain by writing it. tried all the set gains, gains, and the set. its over boosting. max boost hit 215 on the screen, so i think that means 21.5psi i think, dont count me on that. its deff working, heaps of power but then cuts out.
