ERZ to motordyne ART pipes

With that being said is it common for me to get those lower numbers with the supposedly better parts in the stillen and art pipes because it was tuned for other parts?

you can go back every month to the same place with the same setup and each month your dyno will read differently.

most places that always ask for comparative dyno's always ask for them to be done on the same day in quick order with as little variability.
