Using Tuneboy is a snap. Getting a correct tune for that tailgunner exhaust will be much harder without doing dyno time. I'm guessing you might do fine with any TORs, catbypass tune since you'll be keeping the stock headers in place.
I did my own pipes and have the carb filters now covered with a ring of black foam to match the bear claw.
