not getting boost until i get to about 4000 rpm's. usually i feel it kick in about 3200 rpm's then all of a sudden it just started kicking in late. vacuum hoses and check valves are all ok. also blow off valve doesn't release as much air and is quieter.

 

loss in boost pressure?

 

sounds like the primary turbo is cooked....are u getting normal boost after 4k?

 

no loss in boost pressure once it kicks in. not turbocharger problem because was working fine the took it out two minutes later and got this problem

 

That what I am thinking...

Do you hear a loud klunk right when you pass 4,000 rpms?

 

no clunk and only late boost in 1st gear
