SCT X4 Power Flash Programmer

Unleashed has some great customer service for this product!!!: Running custom tune on a 2014 SHO with drop in air filter & 3 bar map on 93 oct. the car pulls harder & has better MPG going from 18mpg stock up to 18.3 mpg with only aem air filter.... All the way tp 21.2 mpg now.... I was very impressed!!!! Torrie is the man

Really easy to use, and it was a pleasure to get a tune from Torrie, he was very quick at responding to my questions and I got my tune pretty much as soon as I got the sct in the mail! Awesome all the way around!

2015 ecoboost mustang. Had a CAI and an exhaust before the tune. They made me a custom tune and answered all of my questions in a professional and timely manner. Next thing I'll be needing are some wider tires!

Very nice unit for the small price. Works great and easy to use. Definitely worth every penny. And the tune custom tune made my ecoboost wake up.

I don't normally write reviews. But the tuner definetely woke my truck up. Truck hauls ass now. Truck use to stop pulling higher in the rpm range. Tuner makes it keep pulling all the way threw. And it pulls way harder from the bottom. Get this tune.

The tune was easy to up load and my car runs much better. Will see how much better it is when I get the down pipes.

2015 Ford Escape - 2.0 Ecoboost - AWD Love it! It smooths out the acceleration nicely and makes the vehicle much more responsive. I would definitely say this, combined with a upgraded air filter, would be the best bang for your buck when it comes to modding a turbo vehicle. If you like your Ecoboost you need this product! The customer service at Unleashed is unrivaled. I ordered my tuner at midnight and had my item in hand with 24 hours. I was able to get my custom tunes loaded into my car within minutes. Thanks Unleashed!

This was my first experience with Unleashed and it was awesome from start to finish. Ordered on Saturday and it arrived on Tuesday. After gathering up some info and emailing it to Torrie, he replied with the tune files in less than two hours. Feels like I'm driving a completely different car. I had one small part throttle drive-ability issue and Torrie kept tweaking it until it was right. Torrie is a top notch tuner and offers the best customer service I've seen. He really knows his s**t.

Really really fast shipping. Great price and the custom tune that comes with it is just amazing. I feel like I am driving a whole new car. Easy to use too. Customer service is top notch!

This product works well I am happy with it. Easy to use love being able to monitor boost and coolant temperature.
