AG 580 1361  and 1362  are production Forester Turbo ROM files.

AG580-1362b  is a upgrade by Subaru to "fix" certain issues with the Forester.

we would recommened that you use the 1362b Rom file for the basis of your Forester tuning.

Note : You can also use the WRX AF531V3 and AF531 MapSwitch ROM files in this ECU so enabling you to use Mapswitch
and UserTune on a MY01-MY03 Forester.
Remember the forester has a small turbo and we would recommened maximum boost of 1 BAR.
