After the initial change in fuel pressure I took it for a run to log it so that I could have some data to rework the VE tables with. As expected this showed large changes from the pre fuel pressure increase 127-128-129 BLM's to the post 110-115 rich BLM's, a quick tweak with the VE spreadsheet and things were a lot better.
The next step was to revert back to the original pre fuel pressure VE table and try changing the injector flow rating from the stock 61 to the new 66, this seemed to work as the initial BLM's were now in the 122-124 range as opposed to 110-115 previously. After another go with the spreadsheet we were back to the 127-128-129 range.
So it looks like changing the injector flow rate to match whats being used does provided some benefit rather than relying on dialling it in with VE table alone.
