knock @ wot no matter how lean/rich

Did you check your injector P/W @ WOT? My car with similar mods is maxing out (100%+) the 550 injectors at 19psi on pump gas! Personally I would never trust the stock O2 readings for tuning.

my logger can't read p/w, but at WOT they read 17.40 ms. pina motorsports said they're probably maxed out, and i should probably step up to 660's. i'm going to check the maft settings right now. i lowered the base fuel pressure a bit and richened up the afc to get my timing at WOT down a bit, and it seemed to help.

thanks to all that have replied. i don't know where i'd be without you guys.
