Just checked logs and I see 25-26psi. Very nice.
Big Powa!!!! How you have no slippage is beyond me lol. Does your clutch hitter or clunk at low speeds etc?
If you are pushing north of 700+ then clutch should be going bye bye.

I have backend and Jb4 running on 25psi also. I will be dynoying this weekend with 93 octane and then with E85 to see improvements etc.
