I am concerned about it plugging into the port also. Will have to know why before I would make the purchase.

Based on what I have read about the Shark Injector it would be a good route for you to go. Much more economical than custom tuning and you can modify it to any other mods you decide to do in the future.

I will google Pedalbox.
