About this item

  • Optimized Engine Tuning For Maximum Power & Performance
  • Speedometer Calibrator for non-stock tires and rear end gears ratio for most applications
  • Automatic transmission shift point and shift firmness adjustments for most applications
  • Adjustable RPM "REV" limiter for some applications
  • Reads and Clears Diagnostic Trouble Codes (DTC's)


The Max Energy tuning provides additional power and optimized transmission functions, resulting in less fuel to accelerate and maintain cruising speeds without the torque converter unlocking and transmission down-shifting to a lower gear. The results are maximum power and fuel mileage. For gas vehicles that come from the factory capable of using regular octane fuel, two (2) optimized tuning programs are provided: one for premium, and the other for regular. Only one (1) power tuning program is provided for vehicles that were designed from the factory to use only premium fuel. For diesels, the Max Energy offers three (3) stages of power tuning for diesels. Even the highest power level, stage 3, maintains safe EGT while towing the maximum weight specified by the vehicle's manufacturer. Hypertech's low EGT, proper transmission shifting, and superior tuning that doesn't require de-fueling.

The box indicated Vehicle " FORD " Specifically! So, I sent the product back. I don't know for sure that the product works for the Dodge RT, or I would have kept it.

Used Regular tune on 2008 Mustang GT with automatic transmission. Something about the tune made reverse gear very aggressive. Pushing the accelerator lightly makes the car light the tires up in reverse. I find this very dangerous. Hypertech support offered one option to fix it. It didn’t work. They had no other ideas. Probably setting car back to stock. Even if it costs you more, I would find a different tuner. Also if you buy from a third party distributor ie Amazon, you do not get the 30 day money back guarantee.

What a difference. I have 35 inch tires on my 2013 F-150 with the 5.0 and the 87 Octane tune. Wow noticeable improvement and my fuel economy is back.

I bought mine for a 2005 F150. The truck runs better with stock program. I have a cat back and good air intake.

I have a 2013 f150 5.0. 33inch tires with 20 inch rims. Decided to buy this tuner really for the speedometer calibration. Day 1 tried the cal, still noticed a split in speeds from speedo to gps. Day 2 tried again and still the same result. Day 3 decided to try one last time and try out the regular octane tune. Seriously felt no difference in drive. I actually noticed my fuel burn faster driving at normal speed. No increase or decrease in the actual avg mpg. Needless to say the truck is returned to stock, im returning the unit. Didn't do anything for me and the price is outrageous. I should've listened to the other negative reviews. Don't chance it on this one.

I purchased this programmer primarily to set my F-150's computer to the slightly larger than stock 285/60-18 tires I'm running and I might be changing out the differential gearing some time later on. I easily updated the programmer via the supplied USB cable and programming the truck's ECM is easy and straight forward. I did temporarily try the regular gasoline tune for a couple of days and surprisingly there was a noticeable difference. I didn't really wring the truck out but throttle response seems improved. I've since gone back to the stock programming so I can evaluate how accurate my tire size changes were and compare my current fuel mileage with what I was getting with the stock tires.One minor complaint is this unit's cost hence 4 stars. For what you get the cost is high IMO but there aren't a lot of alternatives any less expensive.My only other issue was with Amazon and I didn't allow that to alter my opinion of the product itself. It took three programmers from Amazon before I finally got the correct one. They all come in the same box with only the part number sticker indicating the different models. I can only assume whoever was pulling the stock off Amazon's shelves just looked for the Hypertech name on the box without consideration to the many different models. It would have been a 1 star rating for Amazon but honestly this seems to be a fluke and the replacements were all sent overnight FedEx at no expense to me. Unfortunately severe weather in the US turned overnight into three day shipping. Just my luck. After many purchases through Amazon this one was the only such problem I've had to date.

Absolutely worth the money. Simple to use plug, set up, unplug, and done. Performance is better.
