SCT X4 Power Flash Programmer

excellent service I could not be any happier received fast and tune is incredible. highly recommended

The SCT4 performed as it was describe and very easy to install. Excellent customer service from Torrie. I haven't taken the Fusion out for a "spirited" drive but normal driving has been enhanced.

The easy to follow steps that the device displays gives you the confidence to make upgrades. It tells you when to turn the key ( or push the start button) on or off, lets you know its loading or processing and tells you when its done. I load system information and operating files at work and if I could use a device like this at work I could do a weeks work in one day. In addition to being easy to use it came with the cable to connect to my laptop and the cable to connect to the OBD II port on my car. Online support for updates means I can use this for a very long time. The more I use it, the more I like it.

This thing woke my SHO up I mean it literally turned it into a whole new monster!

My 17 ST has taken on a new personality , going to take a little getting use to (600) miles however can't wait for future mods with Torrie and Unleashed!!

Torrie is just simply awesome. I was running a livernoise tune before his, but I can tell you right now his is far more refined and better. the shifts, the power and the customer service is just insane.

My 5 star rating is for the quality of the tune provided by Unleashed Tuning. The tuner is just an instrument to install the tune and is easy to use.

SCT's X4 is just a medium that tuners work through. My 5 star rating is for the tunes Unleashed Tuning offers. The X4 does what its supposed to do. It was Torrie's tune that really woke the car up and greatly improved the driving experience. There used to be huge "lag" in the throttle response. Adding an open cone intake helped this slightly, but it was the performance tune that really made it feel like the gas pedal is directly connected with instant response. Shifts are the biggest improvement you'll notice right away. The car had 225/50/17 all seasons on it and with the tune it was chirping tires into 2nd AND 3rd gear. The car was also more willing to downshift when needed, on the stock tune there were so many moments where I wanted/needed the car to downshift and it just didn't do it. The car got 245/40/19 performance tires a few days later and it no longer chirps into the gears, just hauls ass. That was expected. Besides that, on the performance tune we've seen a 4mpg increase on the estimated fuel economy which I wasn't expected with how much spirited driving has been going on with the new tune. Can't wait to see what the mpg tune is gonna do for it on long trips.

Cant beat this programmer its awesome.

Just amazes me how much this has waken my truck up. Huge gains for just a plug in play and the support is second to none. Must get product, supported by world class tuner. I recommend this to everyone.
