S2 drive is slow, s2 sport is a bit better for the track.

Slow means less boost, which means less heat, and less a chance of me going into limp mode. I am ok with a bit slower in the straights at the track as long as I don't limp....its a real fun ruiner when it limps and I have to pull off to let cool for a couple.

Best I can describe it would be a jittery acceleration. However, a couple of times running up hill I really felt the new power but it isn't consistent.

Please any suggestions to this problem would be greatly appreciated.
I have the same problem. Whenever I hit the pedal very quickly I have a jittery acceleration the first 1-2 seconds. Afterwards, the car is running great. What can I do to solve that problem? Thanks

Since I have RB turbos: Is it possible that my ECU overshoots load target (because of my stiffer wastegates) and as a result the throttle closes? If yes, what can I do? ProTune?

Are you running the RB map? if not ask COBB for it.

If that doesn't fix your problem, contact PTF... They'll fix your issues, and you'll end up with more power

Blend and oct?

I would fill up with 9 gal. E85 and 7 gal. 93oct (contains 5% ethanol here in Germany). In total it should be approx. 100oct and 50% ethanol (E50). Or is that blend too much for fueling?

On a healthy fuel system 50% isn't a problem. If you have a weak link(usually a LPFP) then you may not be able to run that high of a mix. When properly tuned for it a 50% mix can yield some AMAZING gains, just look at Vneblob's PTF thread http://www.e90post.com/forums/showthread.php?t=746740

Fuel system has nothing to do with blend. I am tuning now on E50. Is power output that dictates if you menage or not. Also you cant think octane with e85 since on DI the knock limit is way higher because of the cooling effect of the direct injected charge.

Enrita, would this 50/50 blend yield more power than running strait 104 octane race gas?

depends on the tuning. E85 has cooling effects as well. with E50 i can run very aggressive timings like 3K - 13.5 to 15.3 at redline with almost no corrections at all. engine response is amazing with this high timings.
The beauty of e85 is that is cheap and available at every station (in sweden) . my mpg though is much worse. last tank i did only 280 miles .

In preparation for moving out west where there is no 93 octane, which option do you think will be the best option for performance and fuel consumption?

1. Run the new e85 map with 91 octane mixed with e85.
2. Continue running Stg 2+ aggressive with 91/e85 mix.
3. Get a protune 91/e85 map.
4. Run e85 map with 91 octane and meth
5. Get a protune map for 91 octane and meth.

Thanks in advance.

I'm partial to option 1, modified as needed for your mods and the amount of E85 you want to run. When you don't feel like (or can't) use E85, load a normal pump gas map.

Option 2 leaves a lot on the table IMO, and option 3 will work but isn't really necessary. Meth is a personal decision, but I'd prefer to avoid the extra complexity if possible.

I would try running the e85 race map on e40/e50 and 91 octane.
You would need of course to change scalar in atr.
