Hi, i own a 636 05my, and it is by far the best bike i have ever owed, i have fitted a scorpion race exhaust, but i need some info on POWER COMMANDERS, ARE THEY WORTH FITTING AS I HAVE HAD CONFLICTING ADVICE HERE IN THE UK. PLEASE HELP.
I have a power commander 3 with micron slip-on exhaust and k&n filter, and the map off www.dynojet.com. With that setup i had it dyno tuned and gained 5 hp. Big difference!!! I can feel it all the way through, runs a little rich, but overall deffinetly worth it. Also, the throttle response is amazing. Its got my vote.
