VRSF 7" FMIC is awesome. I have been running it for about two months and I am extremely pleased.
I have the VRSF catless dp's as well, no issues here.
I would look into the BMS meth kit. I've come close to biting the bullet and ordering it several times, but other stuff keeps coming up and I never got around to it thus far. Meth is a nice way to add some significant power for a few hundred bucks.
