I installed a 10 hole injector last night and having problems tuning it with my PCV + WB2. To start, I reset ECU and made a blank map for PCV. It runs great at 0%-50% throttle and if I gradually make it past 50% to 100%. But, if I go directly to 50%-100% it runs super rich and sounds like a machine gun popping off while reading 10.0 on AFR gauge. I have a feeling it is some small tuning issue, any ideas?
