Send in your Ecotec ECU and we can reflash it for you. This includes calibration for our Air Intake Kit, our custom dyno proven VVT cam tables, and adjustments for 91 octane gasoline. This service is primarily geared towards those people who want a basic tune that takes advantage of higher octane gas and our intake kit. Custom dyno tuning will always provide more power, as well as better driveability. We do not "lock" any of our ECUs, so you can have it re-tuned locally without issues.
