My 03 Evo VIII GSR on the dyno at CBRD, York PA.
Car origionally put down 425whp/391wtq @ 28psi with a mild tune on CBRD's Mustang II load-bearing dyno on 93 octane pump-gas. However, with some tweaking and a more aggressive tune, it put down 456whp/422wtq @ 31psi on straight 93 pump-gas. Did some more tweaking and with an extremely aggressive tune and some 100 octane race fuel made 504whp/443wtq @ 33psi (which is about all the stock bottom-end could take). I want to break 600whp, so the stock bottom end will have to go. That's next on the agenda... damn money-pit.
