Can you play with the pinion gearing any?? Change the motor to trans gearing to make use of the added power?? Also, you can play with your exhaust length to find the optimum length for power. I did this to 2 of my sportsters and one had the best power band with 31" straight cut pipes and the other with 38" slash cuts. The only difference between the engines were cam duration! The straight cut vs slash cut can make a difference with power out put. And remember, straight pipes typical push the power band further up the RPM range. Another place to look for a little more oomph is the length and
angle of the intake tract. My TR6 responed very nicely to kicking the carb out to the rightand adding 1.75" to the intake.
A good flat power band will trump peaky numbers any day. I meet a lot of folks that tune for peak power at a certain RPM and then wonder why I can walk away from them if it isn't just a straight line run.
