Models: GasGas MC/EX (2023-2026)
The Ultimate Fix for Off-Road Performance. While the 250 race models are fast, they are notorious for fouling plugs when coasting down hills and bogging in the mid-range. Our remapping focuses on cleaning up the bottom-end response and adding "protection fuel" for the top end.
Plug Foul Fix: Ignition timing and fueling are recalibrated to stop plug fouling during off-road use.
Harder Pull: Optimized fuel delivery means no bogs or flat spots from idle to wide open.
Cooler Running: Added fuel on top keeps your crank and top-end safe during summer heat and deep sand.
Warranty Friendly: We only access the "Tuning" side of the ECU. Dealers only check the EEPROM side, leaving your factory status intact.
 
Models: GasGas EC (2024-2026)
Transform Your Enduro into a Powerhouse. The biggest complaint with the new EC models is the sluggish power valve. We fix the slow opening rates, then manipulate ignition and fuel to match. The result is a bike that finally pulls with the "bark" and "crispness" these engines were designed for.
Crisp Bottom End: Instant throttle response right off idle for technical log hops and climbs.
Power Valve Optimization: Eliminates the sluggish 1/4 throttle transition.
Safe Oiling: Maintains the convenience of the stock oil injection system while ensuring the engine gets the fuel it needs to stay alive.
No High-Comp Head Needed: Our mapping provides enough performance gain that expensive head swaps are unnecessary for most riders.
