Well my answer is no. My truck has been in the "hot" tune for months now and I'm getting the best mileage I've ever had, can safely tow 10,000 lbs over a 10,000 ft elev pass but when I go deep I have all the fuel my injectors can deliver. The shifting responds to the different loads effortlessly.
The throttle graduation is very smooth and takes full advantage of the range in the tuning so that initially it's very stockish then begins ramping up as you go deeper in the throttle. This has made the truck a pleasure to drive. Responsiveness is all about how far you push the pedal.
The tranny shifting is so well managed in the tuning that when driving around toodling along it upshifts early and smoothly. When demand requires higher rpms, shifting is a matter of going a bit deeper in the pedal, and since the fueling is scaled properly it doesn't dump a bucket of fuel, lag and smoke out three lanes. There is no need for different tunes for different shifting because the one tune will shift properly regardless of the situation, just like a stock truck.
If you just want more tunes so you can play with your dial that's fine, but realize that mileage, DD, race and towing can easily be done on the same tune, so if you do have other applications such as a drag tune with earlier TC lockup, nitrous etc you have plenty of free space on the chip.
I'm sure there's a lot of other situations that would require a separate tune that I didn't mention, but for DD/tow/race/mileage you only need one if the tuning is done properly, and seems to me a vendor could really help the users on a budget by offering an inexpensive single tune chip that will in fact do it all.
