SCT X4 Power Flash Programmer

Only 4 stars I think, but just to prove that this is a real thread. The device by itself is perfect and worth having on to view AFRs and temps. The tunes that are worth are the 91 and 93/94. The car feel sluggish on 87 but it does provide a 0.5l/100km improvement. While with 91 is perfect for daily and compares to a stock Focus ST. With an exhaust, cold air intake, colder spark plugs, and a 93/94 tune, the car is to the level of a golf R and Focus Rs. Only thing is that the transmission bugs if you press the gas hard on uphills if you push the car for a long period (5-10 minutes). The engine can handle it, but the transmission not so much. Will soon install a transmission cooler, flush the tranny and put a racing transmission fluid to see if it will fix the issue. The only reason Why I put 4 stars is due the fact that the car has a limiter at 185km/h and cannot be removed and that in sport mode when you change gears manually, it changes by itself sometimes and sometimes it does meaning it will readline and stay there (not consistent). As for the tunes, you will make the car a sleeper. Personally recommend a safe tune with whatever octane (probably towing), 91 for daily and 93/94 octane for racing.

I was going to buy a BDX but since I am going to be tuning an older car in the future, Torrie recommended the X4. It's a great unit. Works flawlessly and easy to read. As far as custom tunes go, Torrie is simply the best. By a long shot!

Got this tuner and 3 custom tunes, I'm now leaving v6 chargers and mustangs these tunes are great. Also if you tell Torrie what your wanting to do with your car you may find he has a special or the parts and kiss your already looking for.

I wanted to get everything I could out of my 2010 Sport Trac and the X4 made it happen. The throttle is more responsive, shifts are snappier, and it gets moving quicker all thanks to the X4 and the Unleashed custom tunes. Bonus...if I resist the temptation to keep the accelerator on the floor, my gas mileage actually is up a bit, too!

Wakes the car up! The feeling of driving it after the tune to now is night and day. Customer service is second to none. Sent torrie the information to upload the tune. Received an email within 10 minutes

I couldn’t be happier with the tuner, tunes and The professionalism and patience from Torrie and Leslie. my 96 lx Thunderbird is definitely benefiting From it and I’d advise anyone to buy from unleashed tuning. The shipping speed and email responses just shows how much this company cares about the customer. The car is at a whole new level now and unleashed has a customer for life.

The tuner itself is great. The support is where the real value lies within. The speed at which Torrie responds to inquiries is astounding. Faster than I can shut down my computer after sending a question, I usually get a response from him. I'm fairly conservative with how I spend my money and 8 out of 10 times will always base the majority of my purchasing decision making on the price tag. Not only was this one of the best price points but the added value of his quick willingness to help, is priceless. Great value!

Excellent experience all around. Thanks Torrie!

After reading a bunch of reviews on focusst.org, I decided to take the plunge and go with an SCT X4 unit from Unleashed Tuning. Even before my purchase, Torrie was very helpful in making my decision. On top of that, Unleashed Tuning provides one of the best, if not THE BEST customer service around. Even after my tune was setup, Torrie promptly responds back which is unheard of in my experience of 23 years in the tuner market. Torrie's tunes are also phenomenal and would recommend them to anyone looking for great gains. Thanks again!!

I've been on the fence about buying a programmer for my 2004 Mach 1 Mustang for quite some time. One of my local friends has a tune from Torrie and I decided to bite the bullet. My package arrived at work on Christmas Eve and I scanned my car and e-mailed Torrie with the details. By the time I got home 30 minutes later I had my very own custom tune sitting in my e-mail. The tune itself is a night-and-day change. Power is increased and is noticeable! My shifting with the TR-3650 was always notchy and jumpy, and I accustomed that to my first time driving a cable-clutch car but as soon as I loaded the tune, with the included rev-matching, all of my shifts were butter smooth and better power delivery. I cannot believe I waited this long to buy this and its without a doubt, the best mod I've gotten. Stop reading reviews. Go buy it. Now.
