I feel you on the hot & hum. I have a n54 w/ AR's (no cats), JB4, BMS DCI's, ETS Chargpipe, etc. Basically all your mods + meth. Been doing so for over 25k miles.

1) Better Driveability: What do you want to improve? Is it handling, traction?
2) Durability: I've gone to the dealer (1x), after my AR's (wastegate had the chirps).
3) Smoother: What's rough?
4) More power: Have you tried E85? Go Meth. How about both?
5) Safer Power: I've never had dangerous power. Log, Log, Log.

What is it that you want to do exactly? What's you're main concern? Seems like you have a big wish list.

I think custom tuning will help you out more towards FBO, but anyways MAP-6 is for custom tuning. Hope you know what you're doing.
