Question. My car is back to stock(no chip) and I have my normal boost, when chip is installed
it runs the same if not a little slower than stock. Can't be the ECU cause I tried someone else's who also had theirs chipped with same result. I had a vaccuum line replaced and installed a TT BPV, still this problem. The car was just serviced by Audi. Could the Mass Air Sensor not be allowing more air in(if that is what it does)? What else could be wrong?

It is a plug above the bypass valve, plugs into...
a solenoid-looking object attached to the intake tubing. Do a search adn you should find some pics for more info.

Also make sure you installed the TT bpv the right way.
Bottom tube should be the return line and side tube faces turbo/boost.
If you have a vag then look at block 003 and see what the readings are at the maf to make sure it is working right.

I am going to use a VAG for some readings while I am driving. I just put my chip back in and let it
do a 10minute TBA, and before I turned the ignition I stomped the gas to the floor (thought I read somewhere that your car can go into limp mode and this was the way to release it), anyway it feels faster now. But still no spooling. I think I just have to keep checking different things. Any harm in removing the N75 valve and then reinstalling?

I have seen audi techs put a bpv on backwards. Here is a
