You said you're not a hot rodder. Do you ride 2 up most of the time, is that why you need more performance? The horsepower number is pretty irrelevant unless you ride your cvo like its a crotch rocket, on the other hand torque is what you really need, specially with the cam you have. 115 ft-lb of tq is pretty decent for most. With a better tune, you might be able to do a bit better.
"Would like to be up in the 115 - 120 range with decent mpg" I assume you are talking about horsepower at peak rpm, decent mileage will probably be in the mid to high thirties. You had your stock cvo engine upgraded to higher compression pistons, a cam that pulls harder on the low end (more torque and less hp) and had it dyno'd. Don't know if you had your heads reworked or changed your throttle body. Kinda going not much different from your stock configuration for performance changes. Before you dive into more major modifications, think about what is your riding style and what you really want. Dyno charts are nice to look at, good for bragging on forums and useless unless you understand what you want and get the right setup. Hope this helps and you don't keep spending $ that don't get you what you really wanted.
