991 TTS GIAC Development Car
What's up Rennlist. Just picked up a new 2015 (at a nice discount) and I'm going to hand it over to GIAC along with my 997.2 TTS for the world's first Porsche 3.8 DI fuel system build. Planning to run as much e85 as possible with as few mods as possible.
Details to come soon.
By the way I'm just a customer of GIAC. No affiliation otherwise.
Cheers.

Will be fun to see the power gains the new fuel system allows for.

There aren't plans to do a full e85 conversion; rather the fuel system upgrade will result in a higher peak fuel capacity at full power. If the current stock fuel system is good for 650 wheel HP then the upgrade may be able to handle 700 whee or more. This will enable me to run a mix of e85 with pump gas and meth injection. Or, just race gas and meth injection. Dyno testing will see how much power GIAC can extract on various combinations of fuel. But the important note is that they solved the fueling issue with this platform and will be able to get enough power to blow up the stock motor and PDK so tuning down the power to optimal safe level while extracting the most power possible is goal, regardless of what fuel is used.

Are you considering another BBi turbo-back?

I am. It seems to be pretty similar to the exhaust for the 997.2. But I don't know anyone that has it yet and I would like to hear it first. Also considering GMG catless and Tubi catless. With the BBI exhaust I could go catless or go with cats since BBI offers the cats to be in the place of the mufflers, away from the turbos (helps keep EGTs lower).

Update: My 997.2 TTS is at GIAC now getting the fuel system done on that car first. Real world testing will be done at an airstrip event at the end of February. Thereafter I plan to sell the 997 and have GIAC put the new fuel system on my 991 and run some mix of e85 with just tune and exhaust. Like anything automotive R&D related, it will take some time but we have waited over 5 years for a fuel system upgrade on the 3.8 DI motor so what's another few months.
