acting weird at wot

[turbo xtc]

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

What is your spark plug gap? Try .030" and see if it goes away.

.035 i'll try that i ran it today using a snap-on scanner and map was reading low signal at idle and i applied vacuum sent a low sig applied pressure and read a little high but nothing out of normal
