Hi, im after a new impreza and looking at a lot of them they're "mapped to 330BHP on V-Power" etc.....so...does that mean I need to re-map it again when I get it home to N.I. where we don't have fuels with as high a ron as V-Power?
That's another £500 price added to car then if that's the case?
Any help appreciated, thanks.

 

If its 97ron you'll be fine as we have that here in N.I, if its 99ron you'll need to get it remapped again.
Find out how its remapped. It won't necessarily be £500 to remap it, it may already have an ECUtek licence, or you could get an open source map - costs around £300. OR find who mapped it and get that mapper to change it for 97Ron, tweaks are normally £150 or so.

Hope this helps.

 

Vpower is 98.

 

Afaik V Power is 99 Ron optimax was 98
