Hello, My ecu claims Impreza 2.0 usa (AH792-5783) 2004 wrx 2.0t engine with downpipe, 3" straight through exhaust cold air intake and a bov... i heard that the current image on the ecu has a fuel problem? basically just wondering what would be the best to reflash with?

Thanks

I believe you need to create an account (free) and login to view the download in that thread.

What kind of cold air intake do you have? I believe that some of them cause bad readings by the MAF and cause you to run lean. I would definitely datalog after the reflash to make sure you don't see timing being pulled from knock.
