So much win Rob! This car has kept getting better and better - very nice!
Just with the E85 making more power when running leaner, I'm curious as to what your AFR ratios/lambda when you were making peak power? I've heard that with E85 the maximum power rich is .7 lambda and maximum power lean is around .86 lambda so curious to know whether this is true for your set up too.
I think we were closer to 0.86 lambda. In the end I'm not sure how much it really influenced the power, because we were simultaneously focusing on the boost and ignition timing, and occasionally making some fuel adjustments. We didn't try richening it back up again at the end to see if it made a difference.

Finally, for us on stock turbo set ups with some bolt-ons, could you do us a massive favour and explain the experience of driving the deuce with THAT much power? For example, from a standstill and rolling acceleration? 
Currently I've got visions of the car shredding tyres, chewing through bitumen whilst the driver is almost passed out from the Gs being pulled lol.
Consider 4 typical scenarios (well, typical in this car hahaha):
1) Cruising in 3rd gear at 3000-4000rpm, anticipating that some quick acceleration is about to be required, then downshift to 2nd and floor it.
2) Cruising in 4th or 5th gear on the motorway at 3000-4000rpm, then downshift to 3rd and floor it.
3) Cruising at less than 3000rpm, then suddenly deciding to floor it and being too lazy to downshift at least one gear.
4) Proper launching, drag style.
...
1) That downshift puts it in the powerband on full boost very quickly, and you basically have yourself a time warp / wheelspin switch.
2) Same as above but with the slightly reduced acceleration of 3rd gear instead of 2nd.
3) This is the situation where a big turbo will always let you down. It can take many seconds for the boost to come on. However, if you're on a long straight road and the lag doesn't matter, then the anticipation during those few seconds, and the rush of feeling the boost increasing from nothing all the way up to the maximum, is awesome in its own way.
4) I'll have to report back on that after I return to the drags some time, and hopefully manage a decent launch. I think even with a good launch there would still be a slight delay waiting for the boost (edit: without antilag of course). But, once you're on boost and shifting near the redline, you stay on boost for the remaining gear changes.
The first 2 scenarios are the most useful and most common...think overtaking.
