The thread is good as it's information we're all sharing with facts as sometimes these issues, since they won't apply to everyone, can be tricky to discuss on a forum.
So log same tune but with WOT at 2000rpm instead of 2600rpm? We've been tuning DI engines since 2006 and I'm also pretty perceptive to HPFP issues (BMW N54s are kind of known for HPFP failure). But there has been absolutely nothing I've seen, logged or witnessed that shows HPFP limitations on this platform. Even with 5psi of boost thrown in.

Are all your logs with the Hydra standalone or do you have any with the stock ECU? Could what you are seeing be a result of the HPFP control logic used by the Hydra?

PS. Also, now that Enhanced Datalogging is released to the public, customers will be able to log all these new channels and provide more data.
