Smarty Jr beta 4

Just loaded it up last night and drove to work this morning. I had the beta #3 in before, running both on the 100hp. The number four seems to have more power and maybe slightly more smoke than number 3. Driving normal I get nothing more than a slight haze when I shift. Most, if not all of the timing rattle is gone when I stand on it. Throttle response also seems better than 3, but not quite as good as the original.
