With the Evo tunes, the shifting seems slightly better but not as firm nor as "tow-minded" as I'd like it to be.
The NQW4 is a TNAA5 calibration which means that it is very similar to the VDH3 and VDH4 pickup codes except yours controls a glow plug module due to the 50 state emissions requirements that Excursions had.

There are a lot of good programs available for your truck.
