SCT X4 Power Flash Programmer

Fantastic flash tuner, very easy to use. This is without a doubt the most noticeable low cost mod you can get. As for the tunes, Unleashed really is the right word, after loading up a 93 performance tune you'll never want to go back to stock. A must buy for sure.

I had a Diablo intune on my previous mustang and I must say the x4 is a much better tuner. The tuner itself is a lot faster an easier to navigate. The software SCT provides is excellent as well. And to top it all off the service here at Unleashed is top notch. Go with Unleashed for your tunes, you won't be disappointed! Thanks again Torrie!

This is the best upgrade for the money. Installed Torrie's custom tune and feels like a totally different car. Thanks SCT and Torrie for a great product and excellent customer service.

The Sct x4 is great a lot smaller than the previous tuner I had. The display and ability to view different gauges is great. Combined with the tune files from unleashed I highly recommend it. Better fuel economy and performance it's definitely like another truck

I'm not doing anything extreme but wanted the right tool for the job. There's plenty of places to get this tuner but the tuning from Unleashed is what ultimately made we want to tune my truck. The SCT X4 is the right product complament for online tuning.

I have only had this tune in my car for about 5 days now but I can definitely say that this was the right decision. I put it in during the snow rush we got to see how drivable it would be in the snow, and to my surprise it did amazing. The tune is amazing for everyday driving but at the same time has the beast side of it just waiting for its chance. The overall torque and HP increase was surprising. The tune is great and the customer service is above great. He was so nice with helping me out and answering my questions. I will definitely recommend unleashed to anyone who is considering a tune.

Torrie is extremely gifted at what he does... Unleashing a car's true potential! He will work with you and your vehicle, unlocking lots of hidden power and torque, tuning it safely for the engine. He always answers your emails in a timely fashion, and I am extremely happy with the way my 2015 Focus ST is running. I definitely recommend this product! I can't wait for more upgrades! Thanks Torrie! - Dylan

I received my tuner promptly and I received responses to my questions promptly. The difference with just the initial tune is outstanding. It pulls hard from down low. Traction has become an issue. The car just feels more buttoned up and refined....that is if you call breaking the tires loose at 30 mph and barking the 1-2 shift refined. LOL. I love it and can't wait to data log and fine tune it. Thanks Torrie!

This is the first tuner I've used. I read the instructions as provided, but it's very intuitive and was very easy to use. I know there are other options out there, but you can not beat the value of how well this product works, especially paired with Torrie's Unleashed Tune and the excellent service that he and his team provide. After providing the specifics that Torrie had requested and uploading everything to my vehicle... all I can say is, "holy hell!" The car (2015 Focus ST) is much more drive-able with just a tad more torque in the low-end, until you start punching it like the adolescent child that this car makes us all feel like we are... and then as my favorite hashtag says #becauseracecar. Normal "family car" when you want and just push that right pedal down, and you really are "unleashing" a beast. Thanks for a great product and even better service. Just buy it.... I can certifiably say that you will not regret it.

I received my X4 and Tunes the same day. No problem downloading Tunes on my PC to the X4 or, from the X4 to my Escape. I took it for my first drive and thought that the changes in shifting alone were worth the price. BUT, the performance of my 2.0L Ecoboost with a 93 octane performance tune were nothing short of awesome! It's like a different, much bigger engine, not like a 122 cu. in. 4 banger. Torrie is a true genius when it comes to tuning! I am very, very happy with my X4 Tunes! William Sells
