What Performance Gains Can the TSP ERM Deliver?
TSP ERM tuning typically improves throttle response, power smoothness, and rideability, with measured horsepower gains depending on engine and tune setup.
Data-Backed Performance Results
Based on internal testing, dyno comparisons, and aggregated rider feedback, the TSP ERM focuses on improving usable power and control rather than peak horsepower alone.
Observed Dyno Performance Gains
| Engine Platform | Peak HP Gain | Torque Gain | Primary Improvement |
|---|---|---|---|
| 250cc 2-Stroke TPI | +1.5–2.5 HP | +1.0–1.8 lb-ft | Midrange smoothness |
| 300cc 2-Stroke TPI | +2.0–3.0 HP | +1.5–2.2 lb-ft | Throttle response |
| 2-Stroke TBI (2024+) | +1.0–2.0 HP | +1.0–1.5 lb-ft | Power consistency |
Results vary based on elevation, exhaust configuration, riding conditions, and selected tune file.
Rider Feedback and Usability Improvements
Aggregated customer feedback highlights improvements in control and ride confidence rather than raw speed.
- 82% reported smoother low-RPM throttle response
- 76% experienced reduced flameouts or hesitation
- 69% felt improved control in technical terrain
- 61% preferred ERM tuning over stock ECU behavior
What the ERM Improves Most
Rather than chasing maximum peak output, ERM tuning emphasizes:
- Cleaner fueling transitions
- Reduced on/off throttle behavior
- More predictable midrange power
- Improved adaptability to terrain and elevation
This approach results in a bike that is easier to ride faster, especially in technical or variable conditions.
