I just tuned my car to Cobb's OTS Stage 1 map and noticed when I go WOT, I can hear the turbo surging. It didn't do it before I changed the maps so I don't know if that's normal.

All I have on the car is a SPT Intake and the turbo was boosting at 17 psi.

 

thats your wastegate actuator, i have the same noise on my bugeye.

 

Ok phew It never did it before so I was just curious.

Thanks for the quick response!

 

i said the same thing to my tuner he told me not to worry that it was normal.
