i just installed the aem wideband a/f gauge. the car seem on the lean side under normal cruising and idle. some where between 14.0 and 15.0 give or take. wot is still way rich so i'm not really worried i'm just wondering if this is normal. i do have intake and open filter plus upper i/c pipe and turboxs bypass valve. (and yes it blows back to intake like it should.) will be dynoflashed very soon. any feed back would be great. thanks.
