your low pressure fuel pump is not sufficient! you see the fuel pressure dropping at high rpm, upgrade the fuel pump, or you will kill it.
also low side fuel pressure in in low torque mode upto 4000rpm... this is because your torque model is way off.
do you have a dyno run for this...ecu calculates only 464Nm of torque...should be way higher.
are you sure your wastegate is closing 100%...this is always an issue in the EFRs, it spools way too late, i got 1 bar at 2800rpm on my car, cam overlap helps hugely here, overlap it until the turbo spools (stock high values from the full load cam table region are sufficient) then retard it, stock it retards a lot after 5000rpm, I ended up at 9-11? on both cams at higher rpm working best.
