SCT X4 Power Flash Programmer

Tuner user interface is intuitive and easy to use I only had two issues: First was navigating the Windows 8 issues with the computer software. Google assisted me with that. Second was that my car battery was low and ran down when I loaded my first tune. After I loaded the tune my car wouldn't turn over! Imagine my horror thinking I'd bricked my car... fortunately I figured it out and after a quick charge all was great (I'll be replacing that battery shortly!) Other than that, loading tunes in my Taurus SHO was easy. I've taken time to try all three tunes Torrie provided, and all are great. The car is so much more fun to drive now!

Purchased my tuner on Friday late afternoon and got it at my door Tuesday at noon emailed torrie around 5 with my info and got 3 tunes back at around 8, I am very pleased and impressed with how fast he made my tunes, and not to mention his customer service wow ask a question and instantly get a reply now that's what you call service. Will definitely recommend torrie any day of the week. And the tune on my sho OMG fast as F*** can't wait to dial this in. Keep up the great work torrie your the best

The x4 is easy to navigate, easy to upload custom tunes, and best of all is Unleashed has the best customer service I have ever dealt with... I think this is a must for all ecoboost owners.. should be the 1st mod that you do!!!!

2015 Mustang V6, Auto, 91 Octane Tune First off, Mr. Torrie McPhail responds very quickly. I emailed Mr. McPhail late evening after receiving the SCT X4 and less than an hour later I had a custom tune. That's definitely superb service and something to look for in choosing a tuner. Flashing the tune over to the Mustang was simple, but be sure to verify the steps beforehand. The warnings the come on the dash during the process is normal. Driving a few hundred miles with the tune was rewarding. The Mustang really woke up and had a 'get up n go' feel to it. Mileage improved a bit since it's not running as rich all the time with the stock tune; I assume it'll get even better once I start driving normal again during my commute versus re-enacting Fast and Furious. I'll probably dyno the stock, 91, and 93 octane tunes, eventually. For now I'm pretty happy with my Unleashed Mustang.

This tune was easy to install start to finish. Torrie sends you great instructions on how to install tuner. Took me maybe 45 mintues to complete entire process. What really impressed me was Torrie's fast responses when I asked questions and sent strategy code to get my custom tunes. I installed the tuner today I was sent a summer and winter custom file and installed the summer. Before the tune my 0-60 best time in 2016 ecoboost was 7.2 seconds. After installing today I ran a 0-60 in 5.9 seconds then I made a few more runs on 0-60 and clocked 5.8 consistently. I am sure I can get this even lower becaue my car is not broken in and has only 300 miles on it.

The X4 is a great handheld tuner, it is easy to understand and operate, installs tunes quickly and hassle free. The on screen controls are easy to read and instructions are straight forward and easy to follow. I've had a few other tuners on other vehicles and this is hands down easier to operate and quicker. I purchased the X4 for my 2012 F150 Ecoboost, I intentionally waited until I owned the vehicle for a few years and was out of warranty. In the interim I added an intake and exhaust system, knowing they wouldn't really wake the vehicle up until I installed a tuner.... well I'm sorry I waited so long, this is how the truck should perform from the factory. It only took the SCT X4 and Torrie to bring it out. So far I'm just running the 87 Octane tune, he also provided me a 91 Octane tune, and an 87 Octane "tow tune" at my request, great customer service!! I highly recommend this product, but more importantly this supplier, Torrie at Unleashed has surpassed my expectations!

I was on the fence about which tuning device to go with. I went with the SCT because they have been around for a long time and I went with Unleashed Tuning because Torrie offers great customer service. The tune turned the car into a different animal. Very good driveability under normal conditions, explosive power under full throttle!

Much quicker than the x3.. plus the color screen is nice.

Overall great product. I had a few issues syncing with windows 8 but once I figured that out with Torrie's help it was very easy. Customer service has been excellent and very fast shipping. Thanks!

torrie not only knows how to wake up a 2015 v6 but his customer service cant be beat! i wish all vendors i deal with were willing to go the extra mile like torrie, you have got yourself a lifelong customer now. thanks for all your help
