A/F Gauge question
Could anyone tell me when you should be concerned about running to lean by looking at a A/F Gauge? An example at full throttle at high RPM mine is showing 1st green "Rich" then goes to the last Stouch "yellow" before the rich. Is there a rule of thumb like mid range stouch is a problem etc?

ya i'm wondering that too, i know my motor is running lean, the plugs are pretty white.......but i got a fpr now and i've gotten it richer up in the bottom of the stoich, and it pulls alot harder but it seems that it's still a little lean, is this guage pretty acurate, and where do you guys run them??

I originally tuned mine with a wideband on the street. On the wideband we set my Zdyne to a safe tune. It just kinda throws me off that sometimes it will go to stouch a bit, other times its on 1st Green rich.

With the wideband we got 13.5-12.8 under full boost. (it would start out in the high 13 range and as the boost and RPM's increased the A/F got down into the high 12's.
