Once again, my apologies as a total new guy. I just swapped out my mufflers for CFRs and have a very slight and occasional, not frequent/often, pop on deceleration. I have been told that a tuner would fix that and that the FP3 is the way to go. I have watched a few videos on youtube, read reviews, and searched for information but cannot quite find what I want. Where do I mount this thing and how? I know it is plug and play but where do I leave it?
