I knew no one else would buy it for me, so I bought it for myself.....a new Diablo Predator r2.02 for $299. Pretty good price? Supposed to be here Christmas Eve. Anything I need to know about loading it that's particular to the Predator? Only plan on the 40hp, well maybe 65hp, OK,OK might have to try the 120hp just for giggles, but just once mind you! lol Honestly, just want a little more power, honest! With it set on the 2nd or 3rd setting, do I need to really get rid of the cat like some say?
