I got my car re-tuned with the Sweet 16 CT15 turbo upgrade from ATS. I decided to take it to a different tuner to get a different feel of tuning styles. This tuner cleaned up my 91 octane map then tuned the E85. I am really happy with the results.
Dyno Numbers

The top number is my 91 octane and the bottom was the final pull on e85.
91 Octane gave me: 305.3 hp and 286.2 lb-ft torque on 15 psi of boost
e85 gave me: 340.0 hp and 311 lb-ft torque on 16 psi of boost

Those are some awesome numbers! I am very happy with the results. I also asked the tuner why the car felt a little sluggish off the line. He took a look at my tune and determined that the timing was a low at the lower RPM range. He bumped it up and it fixed the issue.
Here is my original timing map (91 octane on the left and e85 on the right):
1st Timing Map

Here is my new timing map:
2nd Timing Map

If you notice, the timing on the new tune bumps up really quick at 1500 rpms to get the car off its a**. That was all it needed. The car is now a bigger monster than it was before. I am pretty much at the limit of the S54 transmission and even though the gen 4 3sgte can do 400 hp that is like playing with fire. I will stick with the numbers I have right now. Just to be clear there was nothing wrong with my previous tune. The 1st tuner I used just played it safe. The car seemed to pull better on the stock ECU with 91 octane on the first tune and the dyno numbers reflected. I will still keep a close eye on things for the next week or 2 just to make sure there is not weirdness in the tune.

good stuff man and decent #s for sure! tq looks to remain fairly steady thruout the run, which is awesome...the E85 runs are impressive! the S54 will hold the power, its the starts that kill the diff and axles..no problems with highway pulls, its the launches or even just quick starts and hardish shifts that'll kill the diff or snap an axle at these power levels.

Nice to know because we did leave some power on the table. ATS Racing shows that this setup can do 400 hp on e85. I was shooting for a safe, reliable tune for the track. As far as the diff, I a running an OEM helical LSD out of the Lotus. Can those take the power better?

Holy ****. That's nice. That retune is definitely an improvement with how it blends a little better.

Remember it is with the upgraded ATS billet wheel turbo so it is not quite an apples to apples comparison. But thanks! I am really happy with the results especially because this is running the same amount of boost as before.
