Staying within the same topic but throwing out a bit of a different question...
All I've done to my 2014 GT is the stage 1 performance kit, the Power Commander 5, free flow header pipe and Muffler along with the K&N Filter. The RPM range that my bike spins nearly 100% of its time is between 3:00 and 4,000 RPMs. And when I'm on the highway, I'm very comfortable keeping it right around 62 to 64 mph which keeps it a bit under 4,000 RPMs.
I would love to boost the performance of my bike but not necessarily looking for maximum top-end speed. Where I would benefit from more power and torque would be on the freeway at 62 mph riding into a block 15 to 20 mph headwind where you have the throttle cracked 80% and the bike is struggling to keep speed or at the same time, trying to pass a semi truck without the bike struggling.
What would be the most beneficial modification to boost the mid-range torque and Power?
