14.7 is stoic which is what u want under normal driving below that is rich and above that is lean so 14.4 and 14.2 is normal and at wot it should be rich <14.7 so if that 12.5 is at wot then theres nothin to worry about, and if not then was the car cold and just started up in the morning that will cause it to be rich as well....hope i helped

as said 14.7 is where the car should be at for idle/ no throttle/no load when warm. doing slight acceleration its going to bounce around a bit. at WOT i think most people aim for 12.8-13 or 13.2 ish range for NA. also the lower the number the richer its running, not the other way around. also if its going to 14.4 at WOT don't go WOT unless you don't mind a messed up engine.i would send randy an e-mail or tom to see if they can help you out more.

14.7 is stoich; perfect combustion
The LOWER the number, the RICHER
The HIGHER the number, the LEANER

I think you are looking at it backwards. You need to trust FSWerks and the tune he provided. If your really worried' you need to take a datalog of the A/F with the XCAL so you don't have to watch the gauge while your trying to do a pull. Then send that to FSWerks so they can see what the A/F is doing.

You should contact your tuner , send him datalogs and have him go over what things mean and have your tuner make the needed changes
