I have the code p2563 and p003a. My vane positions start at 89 percent at idle ( used to be 80 until I got efi live). How can I tell if my turbo is bad ? What would I feel ? I can tell you that when I punch the gas I get around 23 psi , but coasting downhill it’s 0psi . Cruising in the highway it’s anywhere from 3-6 psi . I’ve also noticed that sometimes letting off the gas I here the whistle noise , other times I do not .
