P0087, already have hpfp upgrade

[SapperStryker]

I need help with a p0087 code. This coode keeps coming back after driving for a few miles.

I have a auto tech pump. With less than 10,000 miles. Installed on a brand new pump. Ive changed the g410 sensor. Ive also changed the in tank pump. 6.6 bar fuel filter is less them 10,000 miles. Cam follower has less than 5,000 miles i checked a few days ago. and I have a rev. B cam with no damage.

I am running single nozzle dvc-30 meth kit if thats at all pertinent information.

I ran logs on block 103, 106, and 230. Dont have them right now. My request was 129 bar and my actual was about 94 bars in the mid range rpms.

Im still boosting normally and car feels okay. So im guessing the fuel rail sensor is bad?

What do you guys think. The cel light is driving me crazy.

Looks like you've done everything from the ross tech site. Can you swap your hpfp out with a known good one?

yeah. Ill swap an apr pump in and see tomorrow, I really think its the g247 sensor. Anyone else want to chime in?
