I'm having an issue with an aem 30-2310 wideband in an 11 CTSV. So the problem is that the reading on my hp tuners is showing up much more lean that what the car really is I was having issues with the car and making power so I went to the dyno and use there WB and there own was reading 8.9 when my own said 11.6 so my problem all the time was the car was pig rich we took out fuel and car mad a lot of power so I felt I had a bad sensor I changed it still not the correct reading it should read 11.3 ish its telling me 12.9 is there any voltage numbers I need to change or something The car isn't really lean though.
