SCT X4 Power Flash Programmer

as always great customer service loving the tune on my 2010 Lincoln MKS and my new tune on my 2015 Ford Explorer Sport.

I just flashed over today, and I can't say enough about this thing!!! I haven't noticed any less driveability at low end or top end, but it spools faster and boosts higher. I spun the tires between a shift! The shifts are smoother, the power comes on hard and fast! Don't think twice about it, just get it!

Ordered a SCT X4 with one custom tune and vehicle runs stronger! Noticeable difference. Thanks unleashed tuning.

I had a mustang ecoboost after the sctx4 and Torrie's tune i have a different car! Buy with confidence

I liked it easy to use and I liked the custom tune

As advertised. Service was fast and simple. Installation was quick and pain free. Noticable difference in throttle response and power delivery. Stay out of the boost and you'll see an improvement in fuel economy. Would highly recommend.

the SCTX4 is amazing, holds the tunes Torrie did for me and has a pretty cool gauge feature to see the vitals. Since I've bought it I've used it for datalogging also with Torrie's help and it's done a great job. The customer service I get with Torrie and Unleashed is amazing, thank you. My car is running 10x better and it's also nice to have a freindly company to deal with and make that happen :)

great product! easy to use and loads tunes fairly quick compared to others I've used. The gauges are cool too have mine set on boost.

Got the tuner in the mail today. Had a custom tune emailed to me within 30 minutes of the USPS guy leaving. Night and day difference. Car holds gears longer and shifts firmer with a huge notice in power. This tune is awesome. If you have a Fusion Sport, you're doing an injustice to it not being tuned. Its awesome.

The tuner itself isn't my favorite interface I've ever used but I give it 5 stars for Torrie's tuning capabilities and customer service. Very positive experience with Unleashed.
