I have an 05. It drives fine under normal cruising conditions but when i get into it it will builg boost up to 8 psi and then it will loose all power. it holds the 8 psi. And it builds the boost very quickly like normal. I dont think its a boost leak. could it be the MAF or a bad spark plug or coil pack? I have full exhaust, exhaust manifold, uicp, licp, intercooler, intake, and an aem truboost boost controller. Any ideas?

 

Are you tuned with your current mods? Have you done a boost leak test? I would check the basic s**t first.

 

+1..is the car tuned?

 

No not tuned but ive been running the car with all the parts in for the past 3 months and nothing went wrong until now.

 

boost leak or MAF

 

maybe your solenoid went bad on the tru boost ...was it new or used ?

 

It was brand new. If it was the MAF would it throw a CEL?

 

I had a similar problem, for me it was my intake, but if its not that it could also be your wastegate if its still the stock one

 

What kind of bov do you have? And did you check all the pipings for leaks?

 

I'm running the factory recirc. valve. What would be wrong with the wastegate?

 

And what was wrong with your intake?
