I am new to TDIs and diesels in general. But have many years of messing around with cars.... So my TDI seems to be a bit sluggish lately (after the recent cam replacement about 1,000 miles ago). In poking around, I noticed the vacuum hose to the VNT was cracked and replaced that. I also noticed there seemed to be a fair amount of crude in the intake system - not sure it is greater than the 10mm limit but, is there a wiki for the BRM for removal of the intake? In tracking the Torsion Value and boost pressure measured versus target, just wanted to see if my observations are "normal behavior". Basically, when the boost is in the 1000 area, my measured versus target is pretty close if not dead on. But when the car is under load (uphill for example) and the rpms spin up a bit, boost is about 75% of target - example 1500 when the target is 1900, 1200 when target is 1500. I also noticed the torsion value in such situations drops from 0.98 to 0.49. So my question is, is this normal? Perhaps I have a boost leak or restriction? I ask because I have seen systems where lagging below the "target" is not catastrophic, to a degree. I just don't know where those boundaries are here.
