I was wondering this question too. Mine always seem to be high 14s or high 15s and sometimes 16s or even high 16s. Looking at other people's they don't seem to be as high. Joelutz's runs have 1030-1050 O2mV at WOT and almost consistent 13.x BPWs. I have Walbro 255 High Pressure FP, new ACDelco fuel filter, KB Billet AFPR set at 50 PSI, stock 2Bar chip, and new braided fuel delivery line to replace kinked steel original one.
What kind of #s are you getting Greg? Wait a minute I just realized I am thinking Base Pulse Width. I think BPW is a real value while Inj DC. is "calculated". My Inj DC is all over the place. Mine vary from 80 to 117 and it increases with RPMs. The 117 was at the very top of 3rd (4550 RPM) and at that particular point in that run, KR was 0.0*.
