Is it worth it to get an evo v or vi ecu + injectors + walbro + remap and sell my Mines evo IV ecu? Because the Mines isn't precisely made for my car, but a general map? And i'm now doing only 1.1 bar, would like to get it mapped to 1.3 - 1.4 bar? And now i'm always putting octane booster with 95 octane fuel in the Evo, i'd like to map it to only 95 so no octane booster is needed anymore. (what fuel is a mines evo iv ecu made for?)
