That is, like your header test, are we likely to see gains from intakes, exhaust etc disappear once we have your tune in place? I've noticed too that intakes showing gains tend to be tricking the ecu into running slightly more lean. Is it breathing fine already for what we're doing here? Not sure how much additional testing you've done with this but don't want to spend the $ on certain upgrades if there will likely be minimal further gains on top of your tune. If so I'll keep tucking away for FI. Hope that makes sense, on my phone and hard to read what I've typed.

I suggest starting off with the flash and drop-in filter first.
The exhaust gains aren't proven just yet and I haven't had the chance to test any out.
Don's Car showed 0 gain with his exhaust on 6 PSI.
That doens't mean his exhaust isn't good, just the stock exhaust isn't bad.
