However when comparing this to the JDM Auto 04 file I see the following comparison:
As you can see there is no difference! This doesnt suprise me as the JDM car is rated to 190kw in Auto form, same as the STi. so it seems people payed quite a premium for what was simply them loading the JDM map and telling people to run 98 Ron (as well as the slightly less restrictive mufflers at the rear)
So there you go, will be loading the JDM map on my car as soon as my cable arrives and logging knock etc to be sure its running safe on 98

EDIT:
WOOT Cable is here! Will be reading ROMS by the weekend hopefully. Just need to be sure I get all the right drivers for my laptop
