The Electronic Control Module (ECM)calibration is a key factor to both performance and drivability. This stage kit has its own unique specific calibration designed specifically for the Buick Regal Turbo engine. The package has been calibrated to GM standards, and the package is emission legal in all 50 states. As part of the calibration process for this package, the Buick Regal Turbo engine was tested on a dynamometer to develop the base fueling and spark requirements. All of this testing is necessary to develop a package that meets GM standards for performance, drivability, and durability.

Adding this Performance Stage Kit requires reprogramming of the Engine Control Module (ECM). This is done with a Service Programming System at an Authorized GM Dealer. When reprogramming the ECM, the GM dealer needs to call the Techline Customer Support Center (TCSC). The TCSC will provide a Vehicle Configuration Index (VCI). The VCI is good for only one specific Vehicle Identification Number (VIN).

Your vehicle must be taken to your GM Dealer to have the new calibration flashed into yoru ECM.
