GTS Performance Transmission Flash - BMW F8X M3/M4

The GTS Performance Tuning Package retrofits many of the factory software calibrations from the M4 GTS (track special) and M3/M4 CS into standard F8X cars (M3/M4 base or Competition Pack).

Paired with an exhaust/burble tune, the sound also changes noticeably.

DCT GTS Flash (Transmission)

• Smoother, faster gear changes compared to stock
• Massively reduces the “kangaroo” effect (jerkiness) in low-speed 1st → 2nd transitions
• Sharper engagement in Sport & Sport+ modes
• Launch control feels more consistent
• Extra: Alters exhaust tone slightly (deeper, throatier, especially noticeable on stock cars)

Overall Driving Impact is More engaging, sharper car without needing mechanical mods. Transmission feels like a different gearbox (smoother + faster). If looking to go even further, look at our GTS Performance Tuning Package. 

Note: Vehicle coding is performed in our facility in Anaheim, CA. Not available for home or remote-based flashing.
