AA8 Tune - Why no DP maps?

I've got the AA8 tune along with sport downpipe and I can't really understand why AA doesn't offer one of the 8 or so dials to be for those running with a DP? Makes zero sense to me. Why have all these dials if you are only supposed to run the one that it defaulted to? Plus I've got xdrive, so I don't need the boost limiting down low as I have zero traction issues.

So suggestion box if anyone is listening:
Different maps on the dial based on add on parts
Different maps regarding boost per rpms. Some RWD drivers may like the limited boost down low as they'll just spin out with too much, others like myself have no traction issues and could make use of additional torque down low.

Seems like common sense stuff. I know, just get a JB4, but I already have this thing and it's so easy to install and take off I'd rather not switch, but I may have to in order to get what I want.

is there an online manual describing the 8 settings? This is a tune I'm most interested in.

There's no manual, each notch simply ups or down boost by .3 psi. The originally AA8 announcement thread in this forum showed how much boost is changed at each rpm, if you change the dial the boost would adjust accordingly based off the original psi by RPM in that thread. Unless using higher octance gas they don't recommend ever upping it about how it comes even with a downpipe which I find interesting.
