Really works much better than the factory Tow Mode.
I bought to use on my 05 Dodge Rumble Bee for pulling a trailer with 2 large motorcycles on it. Gave me up to 2 mpg depending on conditions, and controls the shifting on hills WAY better than the factory Tow Mode. I highly recommend this !!!

Nothing happens.
Tried the wopping 2 settings for my 99 explorer. Nothing happens. Fuel mileage the same, no more response than normal. Money down the drain since I upgraded to a 2016 Explorer and it's not compatible.

Supertuner results
Bought for 2005 tahoe z71. Even though accel's own website doesn't list my vehicle as compatible with the supertuner, (the box does) it IS supported. Downloaded the updates to my laptop, and uploaded to handheld. 25 minutes. Tuning? Very easy/self explanatory. Tune? Performance 91 octane. Results? Nice, not thrilling, but nice. $268 fairly well spent. (Results not nearly as dramatic as with my 2017 silverado 5.3 /with diablo predator2 platinum. Diablo changed that truck😊)

Great gains
This tuner worked great for my 2013 F-150 5.0. I’m running the performance 93 tune and it has really improved the power and takeoff of my truck. Features are kind of limited but for a cheaper tuner, it’s well worth the money.

Canned tunes, not much options for my 01 Dodge Dakota 4.7L.
It did help with the response on my truck, I use 87 octane and there is a tune specifically for that. There are also tunes for 91 octanes, gas saver mode (not for towing), 87 octane, and return to stock. I looked at HP tuners and that is totally above my expectations or budget. This did work for me since it allowed me to change the size of my tires and it recal'd my speedo. You can also use it to advance or retard the timing of your spark, increase the rev limiter or the speed limiter. A handy tool is the idle adjustment if you're working on the engine by yourself and want to hold it at some value. It goes back to normal once you exit that option. For the price I would say that it's ok, I thought I would get a little more but it's fine.

Not good, easy in theory, but had disastrous results!
Tried to tune my 05 mustang gt, went throught the set up and steps and now my car wolt even idle. I would not recommend this tuner. My car is still sitting, no one will touch it for under 900$
T**!
Will Buy a second!
This does as it says! I own a 2007 Suburban and also a 2007 GMC Sierra. I first used it on my Sierra didn’t think much about it or that it did much. I was wrong I used it on my suburban and found I missed what it did for my pickup. That being said there is one down fall. You can only use it on one vehicle at a time. Once programmer has been used on one vehicle you have to return that vehicle back to stock to program another vehicle. It would be nice if they would allow two or three Programs at one. Other than that issue this think is worth the money!

The ACCEL Supertuner was not performing to what you expected, there was no software available to function, and contacting the customer service disappointing you will receive any response from them directly from ACCEL.

Your busted! These units when plugged into get "married" or "VIN Locked" to one and only one vehicle. When I plugged it in it wouldn't connect. It's married to another vehicle so it now only able to connect to that vehicle. I googled the VIN and it's a Ford. They do this so you can't share or program vehicle after vehicle. It's crazy but they even went out of their way to write "New" on bar code sticker as seen in photo I posted. I was instantly suspicious. Tuner came in orinal box clearly had been open due to damage on tabs. There's no instructions. The cord was wound around it hap hazzardly. It was loose in box flopping around. Also the housing on unit was slightly open. This is not a cheap item, and to purposely try to pass it off as new is sickening.
