A nice set of cams would be the stock 07 or 08 dirtbike cams, they drop right in with no modifications. It was a 2hp gain for me, and only cost me about $65 from ebay. If you are not worried about changing the stock valve springs, then I would try a set of web camshafts grind number 493-813(it is in the dirtbike section) I have these(web cams) purchased for my 488 big bore project. As for the programmer, I have the pc3, I dont really know anything on the pc5. For the price though you might be able to get a excellent deal on a used pc3 from ebay.
