Where is this product manufactured/ assembled?

  • This product is manufactured, assembled and tested in Gainesville, Georgia, USA.

I have swapped a different year engine; will this still work?

  • You must use the MSPNP that matches the year of the engine harness you are using.

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

  • This is a complete package. But there are some accessories you may want to use to get the most out of this unit.

Planning to run the MS3Pro On-board Traction Control? 

  • The stock VSS provides a single speed input from the factory trans, but you will need a FRONT WHEEL VSS for comparison.  We recommend a Hall Effect Sensor
