classic 95wrx

another querie, my 94 wrx is a jap import and it has been messed with a bit, the previous owner said to use an octane booster and super unleaded fuel to get the most out of it,at first i didnt bother but would find the car would hesitate a bit when realy pushed so i got some nos octane booster which sorted the problem, however im now having loads of trouble since my missus put about four times too much in the tank as explained a few treads back, if i want to run the car without the octane booster is it a case of just gettin a uk ecu or is it not that simple?cheers

replace it with a jap ecu (2c,w6,u8 are 240ps or z4 260ps or allegedly 6k 275ps i had problems when i tried to use one in my early wrx hence allegedly works) these will all work with the UK fuel (97+) if you try a 6k i would use 99 ron.
