I am running currently running a AEM EMS 2 with aem uego afr gauge. I am tuned at 12 psi and recently got a serial gauge so i can monitor boost, water temp and the other stuff it comes with. after having a hard time downloading the aem pro gauge software and setting up the gauge I went around cruising to see if it worked. The serial gauge was on but not reading anything, however i saw that my afr gauge was reading in the 10-11s under almost full throttle (and cruising at 14.7) which i never notice it going that low before. I selected the basecal file while trying to figure out how to set the stupid gauge up. Does the afr numbers seem right? did i mess up something? i also downloaded AEMtuner to check if my tune file was still ok and correct and when i tried to connect, it said i needed a password to access or another option to clear calibration file and password. So im assuming my tuner locked it with his passward so the current tune calibration file is still ok?

PS: i've had the tune for maybe 6-7 months. does the tune ever go bad over time? car still feels fine.. and willing to trade aem serial gauge with all cables for aem boost gauge.

thanks
