I am not sure if you have ordered your chip yet but here is another vote for having the stock tune as one of your choices. Stock will be good for going through emissions if you have to do that where you live. Also good for diagnostics, inclement weather and stop and go driving (such as on the freeway).
I've had my Phoenix chip in for a few days and here is what I have learned so far. (stock--65 DD--80 performance--high idle--40 Tow--25 Tow)
Previously have been running a Bully Dog Power Pup in 50 hp (tow tune) for the last 5 years or so....
65 daily driver
0-60 time is about the same as the BD tune but power management is much improved. Biggest change is how the transmission shifts. It now feels like I have a 5 speed because the TC locks between 3rd and 4th gears. The 'shifts' are equally spaced apart as well. Feels like I am driving a TorqueShift now.
I only have two small issues with this setting. The TC lock is fairly hard, much more firm than the actual upshifts between gears. This is most likely a result of the aftermarket TC that is installed and not really a calibration issue with the tune. Second issue is the shifts are a bit too firm at very very slow speeds, such as stop and go freeway traffic. This is when it's nice to have the stock tune available so I can easily flip to stock when stuck in stop and go driving and the shifting is nice and soft.
Overall, the 65 DD is quite refined for the amount of power it puts out. SOI seems less aggressive compared to the Bully Dog tune (which I like).
80 Performance gets with the program quite well. EGTs are managed effectively and seem to peak around the 1250 mark...which is perfect. Nothing in this tune seems to be pushing any sort of boundaries that I can tell. I don't remember what peak boost was but I suspect it was in the 20-22 psi range so there was still some room to work. If I was to change any of my tunes, I would delete 80 P in favor of 100 P. Just my $.02 on this one...
1200 High Idle. Works as advertised. However, I was expecting the PCM to revert to stock tune as soon as the brake pedal was depressed or the parking brake released (like the AIC works). Initially I was a bit concerned but during a test I can easily control the truck with the service brakes even in high idle mode. So now, if I have a TPS or IVS failure, I can select high idle and get myself off the road to a safe spot to work. So, this tune is perfect. Nothing to change here.
I have not towed yet. Will have to wait for those two.
It's beginning to storm here just as I am about to head home. Stock setting will be what I choose. It's hard enough to keep the tires from spinning in dry conditions so once it starts to rain things get even more touchy.
Hope this info helps.
