Product FAQ

Where is this product assembled?

• This product is assembled in Gainesville, Georgia, USA.

Will this fit other GM turbo V6 applications, such as the Turbo Trans Am, Typhoon, or Syclone?

• These vehicles used significantly different wiring and electronics; this MSPNP will not fit factory wiring harnesses other than the Buick Regal version.

Is this all that I need to get started tuning my Buick?

• This is a complete package. But there are some accessories you may want to use to get the most out of this unit.
  • If you are tuning it yourself, a wideband O2 sensor system is a must have for adjusting the fuel.
  • This ECU has an RS232 connector. You can use our external USB adapter if you need to connect over USB.
