I installed a prosport evo wideband about 2 months ago and im in the process of getting retuned and my idle is usually about 14.1 without much fluctuation and my cruising afr's are between 13.9-14.4ish. I'm wondering if this could be my front o2 sensor going out but I don't have any check engine lights or anything. My tuner said that maybe it could be my maf because there was some funky stuff dne to the MAF compensation table by the previous tuned which would not normally work on a regular evo.. any input would be greatly appreciated. Thanks!

i know this is old but did you ever get this figured out?

yes... I figured out that prosport gauges are junk. Once I switched to AEM gauges I didn’t have this problem anymore.
