tonight when i was coming home i boosted up to wot my gauge went to 10 then crept to 13 acts normal but when on wot for a few seconds it started to stutter a little then was fine then stutter again not as severe as to die or like a overboost cutout and my a/f gauge never hit under green(sunpro)it did'nt hit super rich either but stayed at green.i checked my fuel pressure and it stayed at 60psi,plugs look good no salt/pepper and compression was at 125 on all four.I can't seem to understand it almost acts like it is running to rich but my a/f never hit last green light
