So this will either fall under strange situation or stupid question. Depending on which tune is loaded on my stage 1 Roadmaster, the exhaust is either tame but deep with noticeable oomph, or quiet like the original stock pipes.
Both are fine, but obviously one is running better than the other. So the question is, what about a tune would cause such a drastic change in exhaust note?
