Frequently Asked

Everything you need to know before you check out.

How do I install the tune on the vehicle?

You can install the tune through the vehicle's OBD2 port using the eFlash dongle and your iOS/Android device, or Windows laptop.

Is a tune safe for my Engine and Transmission?

Absolutely, when done with a proper understanding of the vehicle and the calibration required to make it all work. Our years of experience ensure that every tune enhances performance without overstressing your Engine or Transmission.

What's the difference between Engine and Transmission tuning?

Engine (ECU) tuning optimizes your engine's horsepower, torque, and throttle response. Transmission (TCU) tuning focuses on improving shift speed, increased clutch pressure, and responsiveness.

What's the difference between Staged and Custom?

A Staged tune is a proven off-the-shelf calibration to a set power level — buy it, write it to the vehicle and enjoy. Custom takes the calibration to the next level and is built around your exact vehicle and needs with optimizations based on datalogs and feedback.

Do I need any additional modifications before tuning?

No. Most vehicles benefit from a Staged tune, but Stage 2 upgrades will maximize results.
