Tuning Chip optimized for 95 Octane or 98 Octane fuel.

• We offer both normal Performance Chips and also settings with extra ignition advance for higher power output with 98/99 Octane fuel.
• An optimized chip makes the torque rise earlier in rpm and the engine becomes more rapid. This is why you cant only focus on peak power output, cause the most important benefits is better drivability and a more rapid engine.
