Reviews: Hypertech Max Energy Power Programmers

I have a 2000 chevy Tahoe 5.7 z71. Old 90's model (my favorite model). Stock trucks back then don't have the horsepower they do now. Slow off the line . But after installing this little gadget. I don't care what anybody says I feel a big difference of the line . Not talking 400 hp but a big difference then what it had .

I put this on my ford 2007 6.0 F250, and on one tank of fuel I could drive from Baton Rough, LA to my home in Harlingen,Tx that's 648 miles on a tank of fuel. I averaged 29/30 miles or gallon. Yeah I'm a believer

If you are looking for that extra power to squeeze out of your truck. This is the product for you! Amazing power gains! Easy 15 min. install. No other modifications required with this programmer. Plug it in and go. Feels like I have a brand new truck. Love that it reads dtc's. Makes merging into and passing traffic a breeze.

This is my third Hypertech Programmer for a Ford truck and thay work geat for pulling a load and better MPGs to.

Nice Program for the money, I have CAI and straight piped exhaust and this was a nice addition to power and improved fuel mileage. The change in the shift pattern in the greatest improvement.

I have a 2010 F-150 with a 5.4L and a 6" Pro-Comp lift with 35" Pro Comp Extreme AT's. Prior to installing the programmer, my truck was getting about 11 mpg around town and 14 mpg on the highway. After installing the programmer, my mileage jumped up to 14.5 in town and 17 on the highway... this alone was definitely worth the investment to me! If you can manage to keep from hammering the throttle all the time, you will definitely notice a difference. The programmer also allows you to adjust the shift points, shift firmness, and calibrate the speedometer for larger tires. My truck shifts a lot more positive now and the speedo is now more accurate when driving. I can also tell that it picked up a little more power...it's not a night and day difference, but it accelerates quicker and has more noticeable power off the line, and I'm only running it on the medium power level. There is also a max power level option, but it requires that you run premium fuel. Bottom line, I would highly recommend this programmer as I have seen great results since installing it on my truck.

Great product, does exactly what it says it will... For my specific application, not a significant increase in engine performance but that was not my primary reason for purchase. I purchased it to change my tire size to correct my speedo after installing larger tires and firm up shifts. It performed both of those functions perfectly and as an added bonus gave me 6 more HP and 10 more LB of torque while retaining regular fuel

Love having this programmer. Gives plenty of options and the HP gain is pretty nice as well. I also added K&N Cold Intake and some flowmasters 70 series to my 5.3l 2004 Tahoe LT.

Instantly added approx 2.5 mpg! Woke up the motor and feels good! I suggest leaving the trans settings alone if you don't know what your doing. But overall worth the money.

Added a lot of pickup to my F150 4X4 with the 4.6L. Gained 1-2 MPG. Shifts are a lot firmer.

helped off road throttle response,helped on hiway overdrive power

Got this today! Also put an AIRAID Throttle Body spacer on! I can tell a difference. Only played around with regular gas option. Waiting on my k\n intake to get here, then going to install and put high octane in it and have a go at it! Also have dumped flowmaster on it.(2008 GMC Sierra 5.3l gas TEXAS EDITION)
