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.

    The wiring simplification and base tune are the two biggest selling points - it also has sequential peak and hold injector drivers, and as it is based on the MS3Pro, there's a bit more electrical noise resistance as well.

  4. Is this using the factory one wire 02 sensor in the pre-installed base tune for the Buick?

    Asked by Godfrey Peterkin
    Answered by the admin

    Yes, the base tune will be configured for the factory narrow band sensor, but it is very straightforward to change it to most aftermarket wideband controllers.

  6. Will it come with a plug kit for 18-pin auxiliary connector? Or is that a separate item? If it is separate, what's the part number?

    The connector is included. We will also sell replacements separately if you lose the one shipped with the ECU.
