AMP EFI. The Ultimate in Engine & Powertrain Control.

DIYAutoTune, US manufacturer of popular, full-featured, standalone and plug-n-play engine management systems is proud to introduce AMP EFI, a high performance engine & powertrain control systems brand focused on high I/O, high horsepower drag and road racing solutions. Their popular MS3Pro Standalone System, released in 2012, quickly tore them from their Do-it-Yourself roots as they increased support for WINNING customers from all racing disciplines due to the US-made quality, realistic price point and vast feature set.

DIYAutoTune parent company, Hoffmann Innovations, Inc. CEO Jerry Hoffmann said “The success of our MS3Pro platform came with some obvious challenges, a new level of customers and expectations from what we were accustomed to. Purchasing a professional grade, race-proven system from a company with Do-it-Yourself in the name introduces some conflict. We had to completely separate our feature rich systems that are obviously a cut above from the legacy DIYAutoTune (MegaSquirt) hardcore-hobby racer systems, as well as provide a whole new level of support and documentation.” Hoffmann stressed the company’s overall commitment to complete customer satisfaction, knowledgeable support, ease of use, US manufacturing and reasonable price points as DIYAutoTune’s five fold strategy that continues with AMP EFI.

AMP EFI rolled out the NEW MS3Pro ULTIMATE Engine Management System on December 8th at the 2016 Performance Racing Industry Trade Show;  Shipping begins today!
