its been obvious since the sr swap that im running too rich... at idle you can tell not all fuel is being burned from the exhaust. everything seems fine power wise and i dont think anything is wrong. i upgraded to the z32 fuel filter and walbro 255 and i have a mbc @12. the upgraded psi has significantly reduced flames from the backfire(vented bov). anything i can do
