I would've never took a log if it wasn't for him asking for one.
I've reached out to Halim in 4 different ways over the last week or so. No response.
This is 4th gear btw. For future reference, the log shows what gear you're in.

I think the issue is that some HPFP can take it and some can't, so BM3 may be reluctant to alter the tune. Just comparing our logs, mine drops 7% pressure in low gears only, but yours is dropping 12% in 4th. I do agree that BM3 OTS maps are pushing the boundaries of a lot of factors, HPFP being one of them.
I think I will do the B48 HPFP mod - it is only a slight improvement (~6% more fuel), but it's enough to pretty much cover the fuel deficit I currently have. I do not want to spend 2K on an XDI pump.
