I've decided to stop whining about the shop I used.
I have a DOA 270 cam on order, hunting down a degree wheel later today. Found a local shop which came recommended by a national vendor which is locally based.
He feels they know what to do with the power curve on the dyno, and the info he provided made me very confident he does in fact know. I'll be swapping the cam myself, then taking it to them for final tuning.
I'm excited to be getting the new cam and learning how to use a degree wheel! Cam should be here in a week or so, but then I'm racing the Elsinore GP on my dual sport, so it'll be a bit until I get back to this.
See you soon!
