ok guys bare with me, im doing this from my phone. have 420a boosted normal 20psi, working fine all summer until recently. now i boost up to ten psi and runs like crap, wideband says rich, however "acts" like it running lean. using PF with stage 5 cal. two step colder plugs. like i said never did this before, its not the plugs, gas, coil, map sensor, missing link, or vacumn leak. so im kinda stumped. any ideas?
