Dinan Turbo: 17psi, 4th gear (because 5th showed slightly less due to heat).

There are some 2psi of headroom (that I tested last summer) in the octane and fuel pump that I left there with my GP500. Because for my daily and track map, I want consistent power.
Dinan turbo is pretty much octane limited, running 17psi under max 95F of IAT that we saw.

Feel free to ask anything.
Well done Sean! Still completely stock fuel system, correct? Got any logs you can share?
