Hi guys, I have a golf vi r20 2.0 TFSI 272, a very curious thing happens to me, with software stock datalog the rail pressure never demands more than 90.17 bar and the obtained one never surpasses the 97bar, these engines should demand and obtain 110 bar, right? the most serious is that the lambdas demanded are 0.72 and those obtained as the rpm goes up to reach 0.91 almost to the cut ... the vehicle does not mark any dtc, how is it possible? the pusher of the pump is new, any idea what can happen?

thanks in advance.

but even if the sensor was wrong, why are the demands only 90.17bar?

regards

Hello, try with new RS4 PVR valve..there is always good update.
In sometimes original PVR go ahead....
