I am in the process of installing my Rinehart true dual system on my twin cam 2000 EG Ultra. They are replacing a stock system. I am working on it after work and it is taking longer than expected. When I finish it looks like rain for a few days. It has the stock EFI and K&N air filter. How big a difference will I notice? I hear the heat is better, but I also hear about mid throttle torque loss. True????

Also, in the future I see a switch back to a carb and cam. What do you guys recommend? Top end is not my thing. I prefer low end grunt. All comments appreciated.
