There's a $75 o2 sim that works on the N55 now, so no worries.

The fabspeed DP, in addition to costing an enormous amount of money, is catted...so it will make less power and be quieter overall...the two primary reasons for buying a DP in the first place.

OP, there are lots of threads about DPs, including the VSRF specifically, in the engine forum. For example:
