Yes, Std Ecu remapped to suit : RB25 Turbo,exhaust, fmic etc. Factory fuel/boost cut raised, 180 kmh speed cut raised, fuel and timimg adjusted and all checked with AFR meter. Not been on Dyno yet but there is a noticable gain in power and driveability. As for costs, you would be better off talking with Toshi, but I paid $230 for 2-3 hrs work. Well worth it in my opinion.
