What do you want to do? Or, how fast do you want to get to 100? and, how much money do you have? Do you want to go with all Harley parts or not? Are you gonna to the work yourself? Have you considered the affect you will have on your warranty?
First step is usually a stage I upgrade - intake and exhaust.
That should bump you up right around 10hp and 10tq over stock. maybe a bit more depending on the parts you went with (my 95" is a stage I with 80hp 88tq). your stock bike is mid to high 60's on both numbers.
