Did some data logging this morning. The actual boost seem to be lower than the specified boost by quite a bit. It shows the most in second gear, but aslo shows up in the third gear roll on throttlw. It almost seems that the boost stays constantly low between 3400 and 4400 rpm. Is this normal or should I be looking for a leak. I have a homemade leak tester leftover from my 92 S4 but I am not too sure how much pressure I should run while testing and if there are any hoses I should plug while testing. Here are some pics of the logs.

Second and Third gear:

This will be fine, and allow you to hear any leak.

How long and how many miles is the DV? Did you ever grease the piston in the DV?

DV valve is only 2 months old, I assume factory lube is sufficient

I think it could be a faulty N75 or MAF

Why?
