Run 1 is 93 Stage 1 Cobb . Mitch got 735 on race fuel. Imagine with exhaust and bolt-ons!

I am not a fan of loud exhausts ..... but BBI may be doing some exhaust work :-) . What "Bolt-Ons' are you suggesting?

(BTW, its my GT2RS - which I am fortunate to share with you and BBI as I have with my others as the first subject to Mod"....

Amazing #s congrats Mitch. What are the differences in the fuel system and PDK vs a .2 TTS?

As far as I know nothing. The 991.2 TTS is a better setup then the previous versions as it uses a new 7 hole injector and relocated the injector to be more in the middle of the head. This actually allows the cars to get with the secondary air injection and allows the cars to run leaner. They have also increased fuel pressure on the high side about 1000psi as well.
