Hello guys I have read on other Wideband topics but I didn't want to butt in on there threads my mechanic mate put a new aem Wideband on for me today 36inches from turbo and tilted in when welded, am running standard boost at moment 0.6 bar on standard ecu with a ct9 turbo when I wasn't driving underload I am getting around the 14's and 15's (that's around 2.5k revs to 3k revs) but when I'm giving it some beans along the dual carriage way on way home I'm getting 17 readings which I know is lean, I have a sard fpr set at 2.3 also uprated walbro fuel pump but any other suggestions would be fantastic please as this has kind of made me think surely the readings shouldn't be that high also on idle warm I'm getting 16.5-17
