The HEX Tuning Flash Tuner by VFE unlocks all the missing GTS Features your BMW M3/M4 should have come with from the factory. We offer this tune in 3 different levels.

Base level leaves your engines power output the same while adding GTS sound features on top. This is ideal for customers who already have a Competition Pack or CS trim level M3/M4, or those running a piggyback tune and are looking for that GTS exhaust burble effect.

For those with Standard M3's and M4's, HEX Tuning offers a ZCP or CS level power boost providing you with up to an additional 30whp and 35wtq.
