Default Low boost issue
everything was perfect after last night, my car lose boost. My boost used to be at 15-16.5 psi at wot. Right now, maximum is ~9.5 psi. I took it to the shop and check for boost leak ===> no sign of leaking. Turbo no smoking, replace new EBCS but wont help. I tried different maps, and even restored to stock map but no help. It still got under boost. My car right now got CS SRI and TIP. HPFP and Cobb AP. i attached log csv file, so anyone could help with my problem ?

I'll be honest, that log isn't helpful, at least not to my eyes.

Both those logs are useless and tell us nothing. Try to get a log in 3rd gear under full throttle or 4th if you can. Start at 3000 RPM, stomp the pedal all the way to the floor, and hold until ~6500 RPM.

Holes in the vacuum lines to boost control? Wastegate arm C- clip feel off so wastegate isnt actually connected and able to close at the hot side to create boost? Seen both of these before on here.
