hey, recently ive had problems with a slow primary spool up, but once it hit 4500rpm the secondary would kick in and they would both hold 10psi to redline, it was lik a 5.7.10 pattern, But now iam only gettin 5psi period, at about 3200rpm i hit 5psi and it holds there to redline,it feels as if the secondary turbo isn't kicking in.
do i have a possible boost leak somewhere? or could it be the the charge control actuator?

 

search for "primary turbo" or "boost leak" in the 3rd gen section.
