  • SHOW style tunes are a cost effective way to safely add some flair to your current setup while still maintaning stock drivability and fuel economy.



    You may not need to visit a physical dealer for a tune. Simply remove your ECU, ship to my location (I pay shipping both ways), then have your ECU reinstalled when it returns. Your engine configuration (2.0 or 3.8) determines what is modified in your flash. All SHOW/mail-in tunes are configured for use with 87-93 octane fuel. There is no mail-in option for E85.

  • Upon purchase, you agree to Alphaspeed Midwest Policies, Releases, and Terms and Conditions as well as any terms listed on documents provided to you by ASMW. Prepaid/free shipping is only available for contintental US based customers.
