Every tune is built with reliability in mind — because power is only useful if it lasts.
- A Custom Tune is a complete ECU flash that directly controls fueling, ignition timing, cam timing, torque limits, and boost pressure — without the need for a piggyback system. This allows the ECU to manage all aspects of engine performance natively, resulting in smoother power delivery, improved response, and tighter integration with factory safety systems. Utilizing logs to ensure that the car is as happy as can be for your vehicle and modifications.
- Backend Flash modifies fueling, ignition timing, cam timing, torque limits, and other key parameters, while still leaving boost control to an external piggyback (such as JB4 or ProTuner). This makes it ideal for enthusiasts who already run a piggyback system and want to unlock more power, add drivability refinements, or enable features such as pops & bangs, rev limit changes, or start/stop disable.
- Pricing and Revisions: all tunes come with free revisions to resolve any issues you may be facing with the tune, customer requested adjustments may come with an additional cost.
- Backend Flash Tune: $229 USD
- Custom Tuning: $499 USD
- FREE Map6 / User Mode Tuning (BEF customers only) Our Backend Flash tunes are designed to work seamlessly with the standard premade maps (JB4 / ProTuner). In most cases, this means you won’t need a custom Map6 or User Mode setup. However, if we review your logs and determine that a tailored boost control strategy would be beneficial, we’ll build one for you.
