No primary turbo after intake removal
 

What could cause there to be little to no primary turbo boost after removing the upper most intake. HKS intake. It is now refitted and everything appears to be attached.

I have about 2 psi of boost right up until 4500rpm then it hits the normal 10psi. This all worked fine until the the upper intake was removed.

Check the vacuum lines going to the back half of the Y-pipe. If the charge control valve or charge relief valve have vacuum lines off you would get some weirdness.

Vacuum lines are pain in the ass lol. Cheers mate will have a play about.

After removing the upper intake again and the vac hoses it turns out I must have pinched one putting the intake back one. Dale wins again! Cheers bud.

That can do it! Glad you sorted it out!
