Built for Your Setup

Every vehicle is different. Your calibration should be configured around your engine, injectors, intake, exhaust, camshaft, transmission, gearing, and intended use.

TuneHappy specializes in motorsports and performance ECU tuning, using an in-house DynaPack chassis dynamometer as well as street tuning and base-map setup to develop calibrations for your specific combination.

This service is for LS Gen 3 PCMs and is intended for properly configured performance, swap, off-road, and competition applications. Hardware modifications may be required depending on the calibration changes requested.

Please provide your PCM information and details about your engine setup when placing your order so we can configure the calibration appropriately.
