I have a wideband and with the fuel trims at zero, I run a 14.7. I am just wondering if something is wrong since I am adding a ton of fuel to get the 14.7/0% Trim. Unless the MAF-T is completely off (by 200cc). Again I have heard that you must richen it up some (set to maybe 580cc) but set at 580 I am still ridiculously lean. It just makes me wonder...
I must have been running super lean with my stock injectors, as I had it set to the same setting I do now, with 650's. It WAS throwing a P0170 (Fuel Trim), so I'm sure I was.
