We have similar experience with bolt on mods. We find that once you go past Gen3 intakes, HFC's, and Cat-Back Exhaust you really should do a tune. You will see gains from Tuning with just those three mods, but we highly recommend getting the car tuned if adding headers or intake manifold just to maintain AFR's (power gains are a plus though).

Yeah, you pretty much hit the spot. I personally wouldn't add headers or an aftermarket intake manifold either if I wasn't planning on tuning it immediately afterwards. Same rule pretty much applies to most sport cars.
