ExperTune Performance software upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure (if applicable). Achieve maximum power from the Dodge Viper 8.4L V10 without sacrificing driveability or reliability by optimizing the engine's performance.
We set out to extract the maximum possible gains out of the 8.4L V10 engine while keeping the operating parameters safely within the confines of reliability and longevity. Once we receive your ECU, our tuner bench flashes it with the upgraded ECU map and we return it to you for easy re-installation; no modifications to the vehicle are necessary. Fabspeed can quickly flash the ECU back to stock at any time.
Shipping costs for sending an ECU to Fabspeed is the responsibility of the purchaser. The ECU will be tuned within 24-48 hours of receiving it and Fabspeed will then ship back the ECU using whatever method it was shipped in with. (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground. If you ship it via Overnight, we will ship it back via Overnight.)
