I think the dyno sheet backed it up just fine. Im sure John has his lying around somewhere.
I think Launch is only running 15psi, he's making a bit more then 240whp. Which is what you said most DSM's make on the t25, on.. whatever boost.
more power = more efficient.
I think that would be proof enough. I guess you need a holy gail of some sort?
I'll let someone else step in if they feel like arguing, I have to get back to work.
