Hey guys and gals well my car was working perfectly. Then today on my way to work i notice that as soon as i hit boost my AEM Wide band started to read around 10-11 and even at idle it does the same thing. But when driving normal and trying to keep out of the boost my A/F ratio is around 14.5-15.3 any idea's ??
