SCT X4: Canned vs. Custom tune
Got my custom tunes last week and installed, tunes are below, I installed the 87 performance:
87 Performance with Street trans
87 Performance with Chill trans
91 Performance with Street trans
I originally had the 87 canned tune installed, only thing I modified was the gear ratio to 3:73 and the shifts points all to +25%. It seems that the canned tune I modified had the truck shifting better and gave more performance, better gas mileage too.
I guess I'll try the 91 performance tune when the tanks is empty, but I was a bit surprised. I'm planning on emailing the tuner at MPT who created my custom tunes. Has anyone had this experience????

SCT X4 Costumer
WARNING!!!!! Recently I used my tuner to return to stock mode and my engine started turning over without me fully turning the key clockwise. Now i have an engine light that wont go away and a truck that will not start or communicate with the SCT X4 tuner. Ford Dealership was unable to reprogram my PCM and now Im stuck with a unreliable 500 dollar SCT X4 Tuner and the cost of a new PCM and another 100 to reflash the used pcm by the dealership. For a grand total of a lost weekend a pissed off wife two screaming kids 900 dollars and one unsatisfied SCT costumer. Unable to return the sct past 30 days of purchase.
