Easy to work just make sure you update it when you get it and make sure radio is off and pull fuse on trailer brake so there is no power on when program is on thanks hyper tech and auto anything

Product quality is good, no problems installing program, however, make sure you read what this will do for your car before you buy it. I was disapointed in the fact I could only change top speed limiter from 105 from factory to 110 with the Hypertech programmer. I also noticed very little change in transmission shift patterns or engine cooling fan settings. But do feel better acceleration and am getting 1-2 mpg increase.

Arrived a little longer than expected but still well worth the wait. Like all 5.4s mine was a bit slow when it came shifting, Hypertech fixed that big time. I've only used a few different settings so far, but let me tell ya i've noticed a huge difference. I have custom exhaust/air intake with my truck and the programmer made even more of a difference. I recommend this to anybody that has a 5.4l super duty. A lot more Hp and maybe 1-2 mpg increase, im still messing around with settings.

After the very easy installation it took about 10-15 min or so and my engine was running smoother, i did the high performance tune and man did i feel the power. before at around 70mph my rpms would be around 1900-2100 now its maximum 1600-1700= gas mileage increase. the ease of tuning the tranny is incredible, with increased shift points and firmness it feels like a brand new truck. well worth the money in my eyes.

noticeable power gains, although nothing huge. Only one tank of gas so far, but appears tune is in a learning stage and MPG seemed to improve with the second half tank of gas. only .4 mpg gain from stock , but hoping for better with the second tank.

This was a great programmer for the 4.6 V8 in the truck. I could really feel an increase in low end torque which is great when i tow my trailer. but best of all my mileage increased 3 miles per gallon but gets better every highway trip!!!

It took only 15 minutes to install.The gain in MPG and throttle response were noticable.I did pick up almost 3 mpg better than before the tune.Getting on the freeway or passing someone is alot easier than before as well.Overall its a good product.
