I found this to be very informative and easy to digest without getting over technical. He uses the VW TDI as examples, but does touch base on our n54's.

This is a great quote from the article:

"boost pressure is a measure of intake restriction. You could put a choke in the intake air path and that would also create boost (but reduce power). A turbo moving a lot of air but showing relatively low boost on a boost gauge means there is low air restriction in the intake air path. Remember, the goal in increasing power is to move more air, more efficiently, not just create boost"

Thought someone might get some eduMacation from it. I know I did.

Yep, very well put.

People tend to see "boost" and equate more boost to more power. Simply untrue, boost is solely a way to quantify the amount of pressure reqd. to move the air.

Hence why a 64mm at 16 pounds is going to make far more power than a stock frame at 18 pounds.
