You will love them. I run them in my truck. The tow tune tows great, EGT's are much cooler than stock. The X-Street gets great MPG if you keep your foot out of it. I keep myself from loading the X-Race. The X-Street has more than enough power for me.
Eric's tranny tuning is perfect for what I have seen.
I would do the following when you get it.
Load the tow tune.
Load the firm shifting with TC lock.
Say yes to dpf delete, EGR removed.
Drive for about 100 miles normal.
Switch up to the street or X-street and do the same.
The shifting will lighten up some.
If you have not done a tranny service on your truck, I would. I have just over 15,000 and just did the first. Had some dust on the magnet. I use my truck mainly for towing, so it looks to be from normal break in.
