hey..

quick question about my air/fuel ratio ..

i remember today when i was racing this mustang GT, that in 4th gear, flooring it, this thing was on bright red all the way down, with vtec and boost on. should i trust that??? i know its hooked up to my o2 sensor thing a bobber in the oem ecu whatever.....

didnt notice any change in performance however or any knocking pinging and the engine is still running!! so ... same thing happens i get red "lean" in 3rd gear floored top end. starts around 4400 rpm and stays all the way through redline.

im figuring its just not an accurate reading or else the engine would have blown up a long time ago??

just wondering what you guys think.
