I've FINALLY gotten some time to ride mine with my Dobeck Performance EJK and their pre-programmed mapping was nearly perfect for what I prefer. The Stage 1 modifications are setup for an aftermarket pipe and air filter. I've got a Two Brothers slip-on and a UNI filter. See the screenshot below for the stock vs pre-programmed settings, but I only upped the yellow setting to 3.5.
If you have an aftermarket pipe you need to buy one of these. It will hands-down give you more in the lower end and you can program them to do just about anything you want.
