Are you guys saying too adjust fuel press. so it reads stoich

at WOT but it will read rich otherwise (closed loop?).

BTW is WOT open loop and part thottle,cruising speed closed loop?

dan couldn't have said it any better ,
.......an air/fuel gauge is more of a diagnostic gauge, then a tuning gauge.........they can be helpful ,but there usually only acurate enough to see if you cars computer and fuel systems are working properly ,.......if you want an acurate guidline for tuning then going to a performance dyno tuner is a sound investment ,or as dan mentioned there are more acurate tuning systems on the market (pricey though)
