anyone have logged ther systempressure on a cis car?

when i started up the car this year everything worked fine AFR 12,1
after some days it now running lean again.

i wonder about system pressure i did not have the sensor so i could log that before so
i dont have any old loggs to compare.

but here is what i see

Idle SP 6,8bar CP 3,2bar

6000rpm SP 5,7bar CP 2,3bar

6000rpm going lean SP 5,4 bar CP 2,4bar

is that drop of SP normal?

i have one new bosch 044 i front and the original bosch 979 in rear.
anyone have found a solution to fit a 044 in the rear?
