Wierd Boost Problem
Ok so I have a 01 1.8T AWM. I have a forge 007, Revo Stage one, and a brand new k03 turbo from Audi. We have went through and replaced both boost controllers, half my hose's, and the vacum pump y thing. Here is the odd thing. When I am under light acceleration, like 1/3 throttle, my car is a rocket, full throttle or if I did not hit that magic throttle spot, feels normal. WTF?

theres the wastegate on the turbo that allows exhaust gases past the turbine to prevent it spinning out of control, this is controlled by the n75 valve (or aftermarket boost controller).
theres a diverter valve that allows the pressure in the intake pipeing to escape while the turbo is still spinning while the throttle plate slams shut (when you take your foot off the gas suddenly)
if your wastegate isnt functioning untill full throttle for some reason, or you have a bad n75 and it isnt opening the wastegate correctly, that might explain your problem.
14-16 psi at full throttle is what a chip would normaly give you. no drop in chips for k03's run over 20 psi unless you have a manual boost controller and cranked it up yourself.
