In my opinion, I would get rid of the JB4 for a software reflash that you can customize to your car. if you get the meth kit, bigger intercooler, and already have things done, you will definitely see more power from a reflash. I dont have a N54, but I'm pretty sure GIAC has a tune and I would recommend them. At least ive had a good experience with their VW tunes
