can you check my uphill video (https://www.youtube.com/watch?v=4BlxzPgQ1Wk) and take a look at Rail pressure it's hitting 800,000 even over 900,000 hPa which when i convert them is 11,000-13,000 psi, and on this video: https://www.youtube.com/watch?v=8TVA7enYPmg they are getting 7700psi max on 4900 rpm and we are hitting over 800,000 hPa on rpms when i feel that the car is slowing down

few months ago we removed the fuel regulator on the right side of the car in the high pressure pump just cleaned and put it back in and we had BOOST in performance for some time after that, later on we removed the pump and put it on a machine to test the pump and we ware told that the regulator is working but with some irregularities so we ordered NEW pressure regulator, when we put the new regulator we also tried with another turbo and that is the period when out performance went to POOR again.

So we have changed the regulator but not the sensor which is mounted on the other side. see the picture:



We don't have warning or alerts that the pressure is too high, but can we have faulty data from the sensor and this data tells the regulator to cut the pressure? which should be the values of the rail pressure?

Regards,
Nikola

Hi maybe the fuel pressure is to low? can you put a gauge on the low pressure side of pump,
partsforvolvo do a after market pump kit at a good price

Hi I found some logs I did with my Delphi ds150e
max fuel pressure is 24098.045614417 PSI at 3084rpm ,at full boost
so you do have low fuel rail pressure, was your car in limp mode when you did the test?

some have used a after market fuel filter and it did fail soon after they fitted it,
I did have a crossland filter with no problem ,
now using Bosch,
can you look at the voltage of the low pressure pump at the fuse then at the pump when it is running, check you have full voltage with it running,

new pump, Dave
