Not really a glitch ... but what is not stated is that BSFC and A/F ratio influence each other, and can't be treated as independent variables. You need to know both these values. Run pig rich and bsfc will go sky high as you blow fuel out the exhaust (not unusual with typical c900 mods), and hp will decrease. The hp calculated is based on the calculated mass air flow (should be close) a/f, and bsfc. Ususal sweet spot for max hp is around 13:1. For program use 12.5 and bsfc about .55 for 2L-T.
