I've been having some boost issues, so I did some research around here and tried a few set ups with manual boost controllers that were posted up.

This is certainly what I'm trying :


This one got me closet to a stock boost I could a Primary is at a nice 10 but as soon as secondary starts up it starts jerking and boost going up to 20 PSI . I've read a few people telling me to port my wastegate but I've seen people with similar mods have a health boost level . Some people post up saying it got up to 14 and needed help . NOT F**KEN 20!!

Any suggestions ? I'm going to try to install a boost controller in the pre-spool line too and block it off to the solenoid and see if controlling the pre-spool effects the secondary boost spike

I used version 2 and it boosted perfectly.
I used Greddy Profec B Spec 2.
Don't forget to plug other side of wastegate control and PCA; otherwise, boost will spike.

Yeah that what I'm going to give a shot expect I've got 2 manual boost controllers.

What was your boost like before this ? I'm thinking there may be another issue with mine, considering its boosting to 20psi on secondary

My mod before the boost controller was only DP & catback (3 in) and had consistent 10 psi.
I added it because I had just bought a high flow cat and knew boost would spike.
At the moment, I have full exhaust and an intake, and running at 10 psi all the way.

were you boosting to 20 psi before you added the controllers?
replacing stock cat with aftermarket usually ends up with boost spike.

yeah, it was - Primary got to 14 but secondary spiked to 20.

I've got the primary down to a healthy 10 but secondary still spiking to 20 psi with version 1 on the photo above.

I'll try version 2 and see how that goes then do some more investigating
