I love this device!! I was lookin into buying the previous model for a while now but when I saw the new x4 I had to try it. I could immediately tell the difference of my car. A lot more responsive, better acceleration, better harder shifting, and much more. I do like the available options that are given in the preloaded tunes. Hopefully pretty soon I can use this x4 and go get it dyno tuned. If you are gonna spend money on your vehicle to get performance, the SCT programmer is a great way to start. I recommend this to anyone wanting a little more zip out of there car. With this I was able to get a 30mph punch and have the tires scratch and when it hits second it scratches also.

Andrew Dunnagan

A night and day difference. I had a bullydog tripple dog powerpup before this and my truck didnt run right and shifted very badly. Now my truck runs perfect and has flawless shifting.

BJ McCarty

Great upgrade. Size, display, options. Nice work folks.

Brad Bolz

Installation went easy enough. I had to update installation program by installing it on my windows based computer. Then I connected the tuner to my truck and after a bit of communication, I needed to update the tuner itself. Then, I let it install the basic program for my truck. Then, I installed the performance program. My truck has gone from 17.6 mpg to 20.0 for a 25 mile test run. Tomorrow, I remove the diesel particulate filter and see what that does to increase my mileage. Easy enough an internet savvy Cave Man can do it. If you can enter the password on your home wifi, onto your computer...you can do this.

First impressions for this device rock! The user interface with the color screen are amazing. It updated via Wi-Fi perfectly and quickly. I am running the stock 87 tune on the truck now and it feels better than stock. I will have a custom tune loaded on it shortly.

DANIEL BLEVINS

IT WAS GREAT MONEY WELL SPENT WHEN I GOT MY SCT X4 I HAD TO DO A UPDATE SO I CALLED SCT AND THEY WHERE GREAT TALKED ME RIGHT THROUGH MY PROBLEM AND ABOUTH 30 MIN LATER I WAS TUNING NY 2015 GT FOR A SCT EMAIL TUNE ITS GREAT REALLY WOKE MY GT UP I WAS SHOCKED AT THE DIFFERENCE….AT THE TRACK CAR PICK UP 5 MPH FROM 109 BONE STOCK TO 114 MPH!!!!! MONEY WELL SPENT GREAT JOB SCT NOW CANT WAIT TO TRY A CUSTOM TUNE!!!!

Daniel Curtis

FINALLY! a product that works with my NON-SHO Taurus. This thing is great. Only downside is that it only comes with a low octane tune and you're limited on what you're able to change. But even with that the difference is awesome. I added a custom tune and now its a complete beast.

Danny Brown

i like the ability to be able to monitor the parameters and download custom tunes

Just installed a JLC CAI and the SCT X4 on my 2015 GT Premium bought from CJ Pony. I had already updated the X4 and when I started the flash it gave me an error message saying that a further update was required. Plugged it into my computer and used the update software and a quick update happened and it said I can now go back to my car and proceed with the update. It went flawlessly after that. This is my first mod to this car and I have to say that my money was well spent. Wow, this thing gets up and goes now! Even in "normal" mode the throttle response is greatly improved. I'm impressed with such an easy mod. I suspect that most of the performance gains are due to the SCT flash. The combination gives a real seat of the pants kick. Nothing but praise.

Dave McCoy

Ordered my X4 from Steeda, and it shipped with a clear plastic cover that left a very sticky residue on the face of the tuner. Called SCT and they were genuinely just as upset as I was. Turned out their vender made the screw up. SCT replaced it with absolutely no hassle, and shipped it overnight. I am VERY impressed with their customer service! Special thanks to Felix for assisting me. As far as the tuner itself goes, it really opened up my 3.0 Fusion. This car now rips! SCT has a customer for life.
