Hi, I am having my VW T5 2.5 PD mapped on Friday as I have just fitted a hybrid turbo and tubular manifold.
As I have an accurate negative pressure meter for setting up boilers I have fitted a measuring test point in the top of the airbox to see how restrictive it is at the top end.
Just wondered at what amount of negative pressure would you start to restrict power?
