Pure800 is compatible with Dorch Stg2 up to 85% ethanol. At that percentage the injectors can start to become a pinch point at higher boost levels.
I've been told by numerous trusted sources that E50 is the sweet spot for the 600-650 WHP area. You don't really sacrifice much in the way of octane to do 50 instead of 85 and it is less stress on the injectors and LPFP than 85.

I'm at 602/610 wheel, AWD and don't plan on going much farther on stock block since this is my daily. If you want more power than that, it's possible that a LPFP is needed, have only seen a few people talking about that so far.

If you want to run E30 on the stock turbo, you can do that on the stock hpfp with an OTS flash map.
I really think I'll be happy with the power I can get with the dorch stage 2, e50, and pure 800.

I am running e30 and the bootmod3 stage 1 e30 map today.

Thankfully, my intake and down pipe will be here any day now. So I'll be running stage 2 e30. I'm looking forward to that.
