Dyno tune needed after header install?

[Teddy-T99]

Would I really need a dyno tune after I install headers or is this something I could program from a handheld tuner?

You do need a tune revision, but not necessarily a dyno tune. You could get an email tune to richen up the a/f a bit.

This. Also if you're going to a catless mid pipe after the LT install, you'll need the rear O2's shutoff or MIL eliminators.
