IMO maybe the reason is a faulty LPFP, filter, PRV.....

So make a log 2/230/246! Wink

How a faulty LPFP can change your requested rail pressure by ECU?

BTW:
Do two logs @ WOT from 2500rpm to rpm limiter
then two logs @ WOT from 1500rpm to rpm limiter

If you see which is the issue , i will tell you how to solve it.
