Questions on Tunes

[magicc8ball]

I have been looking at different tunes and tuners for awhile now and recently decided that PHP would be the way to go.
Here are my tunes that I have picked.
1. Stock
2.80 DD
3.100 Per
4.120 Race
5.65 Tow
6.High Idle w/ anti theft or whisper

Before I get to the questions I want to say that my truck is used more for DD than towing.

One of the questions I had was for those that use the whisper do you still have to just shut the truck off in drive through's or not?

Another question is about the 65 tow, I do not tow that often as well but I just picked up a deer lease this year and can see my self towing a camper or 16ft trailer with 4wheelers and anything else you would need. For this reason I opted for a 65 to rather than the 80 tow and if for some reason I had to tow something less than 7500 than can just use the 80 DD.

Last question is on should I go with the Phoenix or just get the F.U. chip?
I do plan on adding more mods to the truck like BTS Tranny, Regulated Return w/ Fuel Bowl Delete, Injectors and other things. This wont be done all at once but as I have available cash.

Thanks in advance.
