Do you have more details on the scope of what problem you are having? Just posting a datalog with no other symptom information does not really help us help you. It looks like your hpfp is making frp when you push the throttle and at idle the frp looks normal 3-400 psi

My FRP sensor just went out(just replaced it)
Mine would misfire like crazy at anything above 2.5k or like 25%throttle.

You monitoring misfires?
Code popped up for FRP too high but looking at data logs I was down to single digits at WOT

It's up to you if you wanna risk it but I've got a spare sensor on a 1.6EB motor here you can have.
PNs match. 63k on this motor so it's probably still good.
