"I bought the hypertech max programmer for my 09 focus. It was ok in that it gave the ability to change rev and top speed limiter, as well as a few other things. Overall power gain and gas mileage improvements were minimal tho. Probably better for larger engines and diesels." —Jason K from Morgantown, WV bought a Hypertech Max Energy Programmer for a 2009 Ford Focus, 2.0L 4-cyl. engine.
