Your cart is empty.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.

Did exactly what I expected. After going through the update (you have to do this no matter what to get it set to your vehicle) it really isn’t a big deal as long as you read. Heard a lot of negative about the having to update before using it. It isn’t vehicle specific. Other than that, it prompts you through the process and works just as expected. My 09 Silverado on 35” tires has a working speedometer now and AFM Delete is perfect. Should have purchased a long time ago!!

Used on my 2015 gmc all terrain and nothing but positive feed back. Easy installation for More torque, hp, and better gas mileage. I’ve been telling everyone with at truck that they need to get one totally worth it.

The programmer didn't have the programmation for my 2008 Z06 but I went on the website throught the provided CD to upload the correct calibration, it's straight forward and easy. Afterward, the programmation went OK, quite easy to program. You can tell the power difference compare to stock calibration, it worth the investment.

Iv only had the tune on my truck for a few days so that's why I went with 4 stars. I am honestly impressed with it so far though. Havnt noticed any gas mileage increase as of yet but that could be due to the fact that I have it sent on the performance tune and have had a heavy foot since. My 2011 Silverado seems to love the new tune though. Running noticeable smoother. Shifts are much smoother as well. Main reason for purchase was to turn off that miserable AFM. With an aftermarket exhaust system there was a nasty exhaust note at cruising speed when the truck would go into V4 mode. Or a "tone lock" some would say. With this programmer I was able to disable the AFM system eliminating that "tone lock."there is also a handful of other features that was a plus for sure but they are listed in the description so I won't get into all of them. I will say that this programmer paired with the handful of performance products I have on my truck (K&N intake, jet MAF sensor, jet throttle body spacer, & flow master duel exhaust) is a must have.

I bought this mainly to disable the active fuel management. It would not install without an upgrade. Installed software on computer to update the programmer. Programmer update failed as update software is out of date. Had to install updated installer. Upgraded programmer and reprogrammed the computer in my 2008 GMC Sierra 1500. Went for a test drive with the following results:1. No discernible change in power2. No option to disable the active fuel managementI called customer support and was immediately told the option to disable active fuel management applies only to 2009 and newer vehicles and that there were no plans to include 2008 and prior models. So why can't they say this in the product description instead of forcing the consumer to purchase and install to figure out if the option is there or not? Huge waste of time and money. This went back for a refund! To make matters worse, the claim of increased power is a joke too. All of this for ONLY $330!!!

I've had this programmer over a year now and has done exactly what it says and then some! It took a few times to get it right as for as programming goes but well worth the cost. I was initially afraid to add any programmer to my truck bc of the bad things I heard they can do. I took a try and WOW what a difference! I have it set on level two and my fuel mileage has gone up 3 mpg city and 4-5 on hwy... Even though I have a heavy foot! I changed the calibration, and a few others and the performance. The thing has turned my truck into a race car! Power is amazing... I'm actually afraid to turn it to level 3 bc I'm already catching 2nd and 3 gear shift skids and peeling the rubber off my 305 terra grabblers. Amazing product. I have 160 k miles on my truck too and purrs like a kitten. But, this is the first of heard of it limiting your engine life. Will have to check in to that. Bought 2012 review written 1/30/14.
