"With the discounts that AutoAnything offer made this a smoking deal! I am very satisfied with this programmer. It really "woke" up my truck." —Jason W from Billings, MT bought a Hypertech Max Energy Programmer for a 1999 Chevy Silverado, 5.3L V8.
"First programmer I've ever purchased. Easy to use. Immediate power gains. Haven't noticed any gas mileage because my foot's always on it. The only thing that bugged me was that I was unaware I needed an ECM update before it would program my truck, which ran me an extra $89. Overall, well worth it." —Glen F from Westminster, CA bought a Jet Performance Programmer for a 1999 Chevy Silverado.
