ECU Reflash – Monster Turbos (AKA) Mailbox Tune
Remove factory restrictions and unlock the performance Motorcycle left on the table. The Monster Turbos ECU Reflash raises the rev limiter, removes the 186 mph speed limiter, sharpens throttle response, and improves cooling—perfect for aggressive street and track-focused Motorcycles.
This reflash delivers stronger pulls in the mid and upper RPM range while keeping engine temps under control when it matters most.
Features:
- Rev limiter raised to 11,300 RPM (+500 RPM)
- Top-speed limiter removed
- Timing adjustments (TRE strategy)
- More aggressive secondary throttle operation
- Radiator fan activates at 90 °C / 194 °F
- Stock O₂ sensor disabled
Plug it in, wake it up, and ride it the way a Hayabusa was meant to be ridden.
👉 Order now and unlock full performance. Call today and lets talk about getting you more out of your Motorcycle.
