can a standard type ra v5 [classic] be run on super unleaded and be ok or should it be filled up with super unleaded and octane booster

or of course remapped for optimax would be the ideal

who in,,or around newcastle, can remap the car or who knows these cars and can sort out a lack of power issue with this car

 

definately octane booster also................................

based near the "angel" if its of any help??
