With full control over a wide range of critical engine parameters, you can create and store up to 10 custom tunes for any situation, from towing trailers up steep grades to passing slowpokes on the highway.

You don't have to get your hands dirty installing the SCT X4 Flash Tuner. Just plug it into your OBD-II port, follow the on-screen prompts and you're ready for action. Plus, it doubles as a digital gauge set, giving you real-time readouts of all your key speed stats. And with WiFi built in, you can update your X4 without ever connecting it to your PC. It even comes with a 1-Year Warranty.

I had never used one before & from start to finish, I was done in under an hour. Really easy to use. I definitely noticed a pleasant increase in power & gas mileage. I recommend!

Very good pre loaded tunes. I bought this as a Christmas gift for myself, and sct does great with their tuners. It does look a little ugly and cheap, but it works great. I use the 87 tune on my 5.0 f150 and it feels like it gained a lot of power. Also fuel economy when driving reasonably is about 2mpg better just on 87 octane. I was getting around 19 combined in negative temperatures. Highly recommend it if you can get past what the device looks like.

Disable veteran, got this car for myself. Don't drive much, but I do like to have a little muscle when I do.

Comes with preloaded tunes but not ad many "customizable" modification options as I was led to believe. Had to order a custom tune because of this. Car runs with my mods and wouldn't run without it so, yeah...

Good programmer
