    Is there much difference if I get my truck tuned before or after I put exhaust on it?

    Hopefully getting a local guy to tune my truck soon but don't plan on getting exhaust for awhile, when I do I'm going with a Corsa DB.

    Just wondering if in my case where I only have a Airaid MIT that an exhaust will really benefit the truck that much with a tune done before or after the exhaust?

    You getting full exhaust? Long tubes, deleted cats? If so doesn't really matter. You can run that stuff without a tune, or get tuned then exhaust and have it retuned. Considering they're free

    Just do it after to get every bit you can, not that it will be a huge difference...

    Ya my plan was just to get it tuned this month.

    Cat-back Corsa system is in the works for later this year then after that I won't be doing any performance mods for awhile.

    Exhaust swap provides little to no performance benefit, and there should be no tune changes.

    Only reason for tuning after is if you're doing headers and need to delete the rear o2 sensors for no cats.

    Headers do provide much more gain than a cat back system.

    no problem, the only part of the stock exhaust that is restrictive is the muffler, everything else is actually pretty good.
