hey guys im just trying to get an idea on what I need to do and when to do it. I have a 2012 c6 grand sport with an axle back exhaust cold air intake and diablosport intune. I am planning to do a lot to the car most likely within the next few months I was just wondering is it wort it to go ahead and get my car dyno tuned for my intake and exhaust or just keep the diablosport on until I get my headers and full exhaust and do a tune then?
