mate just a quick reply on your ecu.. why remap it if it's already comes from japan standered tuning for above 100octane fuel.. japans premium is rated at 102octain .. so dont stuff around with it i recon .. the only thing i would sugest is running a after market ecu like i have for max tuning .. i have a microtech LT12 bigggy baked.. runs well since mine is all stock .. on 10lbs it's doing 180rwkw..and mine is a auto to..
