So recently boosted a d16y8 and finally past the break in stage with problems. The car recently started to misfire and run like crap but only when giving throttle input (could be 5%-100%) and it breaks up and backfired but isles fine. When it backfires and runs like crap the A/F reads lean like 15-16/1 but I pulled the plugs and they look normal. Really at a loss and not sure what to do. The car will idle perfect which kills me.
