If I recall correctly, around idle HPFP should be somewhere in the region of 700psi idle, and under WOT around 2k

If it drops below 1500 psi, your HPFP maybe failing.

LPFP above 60 WOT is fine,

Driving at 20 mph isn't gonna give a good idea of HPFP or LPFP

Also can you post logs on Datazap.me (it's free)
