Overall I'm happy with the purchase. The tunes it comes with did make a difference. Mainly bought it to get full economy back after lifting 6" and adding 35s, with the 91 tune there is a big difference on how it drives and feels real strong. Currently changed it to the 87 just to see if I could do better on economy. With the 91 time I gained overall 2mpg from 12.5 to 14.5 on average. 87 currently at 15mpg.

I purchased the SCT X4 for my 2006 F350. I mainly wanted more towing power and better fuel economy. I achieve both of these objectives. Initially I hooked the SCT X4 up to a computer to do the update, but found the wi-fi worked easier to update the programmer. I am happy with the results of using the SCT X4.
