The C3C Evenflow Max Boost upgrade is a vehicle upgrade featured in RAGE. It can be purchased for 30 Racing Certificates for the Cuprino. Similar to the C3C Evenflow 2x Boost upgrade, this provides a great advantage in Vehicle Combat, especially when combined with the Magnum Grill, but increases the effectiveness of the pair. The damage done by the player's vehicle ramming is increased even more so than the default Boost.
