I installed my Dorch Stage 2 HPFP on the weekend. I'm running E85 via a custom BM3 tune. It's running really well, besides cutting out momentarily at idle / low load. Very strange and it wasn't doing this with the OTS 93 tune, so I'm hopeful it's just a tuning thing.
For anyone that's interested here's the logs:
3rd gear pulls -

Idle with the HPFP drop outs -

Note the tune is displaying as stage 2 E30 as I was originally going down that path but realised the stock HPFP wasn't up to the task. At that point I got the Dorch and arranged for the tuner to go full E85 instead.
Also this is just the first basic tune that is yet to be revised.
