It was extra, i had revo stage 1 on the car already, so i payed 50quid to upgrade to stage 2, then 40quid for the 4bar. But if you go stage 2 Custom Code they dont need a 4bar. All depend what map you have on the car already and what mods you have really mate. CC wanted 400quid for stage 2 map, totally worth it, but for 50quid i couldnt say no to Revo
