I'll be up there tomorrow then with a friend. I made 333hp on Seans Mustang dyno last year, but I put slightly larger injectors in since then and retuned it. We'll see what happens tomorrow. Anything under 375hp and I'm disappointed if it's a Dynojet. Mustang dyno I want at least 345-350, haha.
I checked the data logged info on the Gameboy. I did only get to 14psi, so I was 6 - 7psi short of what it should do. I'll get on the same Mustang dyno I was before sometime and see what happens. I'd imagine I would have been closer to 350 if not a touch over.
