I have an 06 and seems like I'm getting boost cut off sometimes. Someone told me to use the AP1 throttle body. My question, whats everyone using?
Do you modifry the AP1 body and use the AP2 intake manifold or change to the AP1 manifold also?
(I know if its the throttle body cuz I tap on it and starts to work fine)..

Thanks in advance!!

 

Your throttle body is fine. Are you turbo or supercharged?

 

Turbo

 

Check your vacuum lines and your wastegate line. You said it is only happening some of the time?

 

works fine when u tap it? what?

 

I unplug the map sensor and tap the body with a small hammer.

 

What MAP sensor are you using?

 

Stock

 

What is your target psi?
