I will provide you with with the best answers to the 4.4-4.6 questions. Every car will be different for sure but I get the sense that you're pretty skeptical.
I'll enjoy getting your reaction BC.

Not skeptical at all. Just due diligence. I always do a value equation. How much improvement in HP/TQ can I expect per dollars spent.
If I have your dino numbers in your current setup and then the dino numbers after only adding headers, no tune, I can get some idea of what I might get accepting your numbers as the minimum.
Dino numbers with tune added before headers and then add headers would be OK but that would not likely optimize your application. With only numbers with a tune to go with headers I can't separate the contribution of the tune verses the headers alone.
Thus far, I an running the Dinan tune with meth so that when I am not on nitrous I still have decent performance. That means I haven't retarded the timing, it is more advanced than stock. I can't do a tune that needs more timing advance because of the risk of detonation on nitrous. That was the primary reason to add meth, synthetically increase the octane to be in safer zone. That's the long story reason for my request.
