Stock civic fuel pump in turbo gsr???
Hopefully this is the problem... My wideband is reading really weird. I have a stock civic ej1 fuel pump for my turbo gsr setup. Would this cause my a/f ratio to run really lean? like 16s lean?? The stock o2 sensor is also broken, so it should be running mega rich... which it is. Its running 13's at idle which I know is very rich, but when i boost up to 10lbs it goes up to 16s. Now its not tuned... PLEASE dont tell me to go get it tuned, because I know it does need one to run perfect, but it shouldn't be running this lean on a basemap. If anyone can shed any insite on the subject, Id greatly appriciate it. 
. im running dsm450's btw.
