i did a boost leak test and i have air coming out of the throttlebody shaft seals. i called accufab and they say it is normal because air has to go somewhere. my engine wont idle under 1100 rpm and this is where i saw the first boost leak, and i am sure it is a vacuum leak too (havent tested for it though). after i figgure this out i can mov on to the intake and see if that has any leaks.

does anybody else have this issue?
 
Lol, not true. Had a dsm turbo car and started having surging issues, heard a whistling coming from the tb, turned out it was the seals. Changed them and it fixes the issue
