I've found BOTH my DSM's were fast! I'm just pointing out the fact that they get pretty squirrelly at high speed.
I've never looked into RX's much, though... I have a basic understanding of the rotart, but have never considered it's relationship to forced induction situations. -Interesting
I didn't mention, though, that I live in The Rocky's. Vail, CO to be exact. AWD is quite desirable here
