Well recently I installed my AMS 30R turbo kit with Perrin Inline boost controller. I have one line running from the bottom nipple of the wastegate to the boost controller and second one line from the boost controller to line I teed on the intake manifold. Then I have the discounted the stock boost soleniod BUT I still can't run more then 14psi. Can the problem be since I didn't cap the stock boost solenoid (two ports)? Also tried adjusting the boost controller it didn't help. Any advice would be greatly appreciated.

Also note I still do have my Xede still on the car BUT the boost table are zeroed out.

 

Okay a little update on my issue. I took off the Xede and plugged in everything the way its supposed to be on stock ecu. But still I can't run more then 14psi with my Perrin boost controller.

I am think of re-routing my boost controller, right now its of a vaccum line of the intake manifold right by the regulator. I want to try to tee the BOV line like everybody else does. Do you guys think that might be a difference? Any suggestions?

 

its needs to go to the wastegate and the turbo inlet nipple. or does the 30r not have one ?

 

I have the AMS 30R turbo kit. Right its running from a the lower nipple of the wastegate to the vaccum line on the intake manifold right by the ragulator and in between is the perrin inline boost controller.

 

If you can't run more than 14 psi with a MBC your problem is not ECU related. You either have a major boost leak, have the boost controller hooked up wrong, or the boost controller is broken. Your connection points are fine for the boost controller, are you sure it's not installed backwards? If you are sure of that, then check for boost leaks.

Well I just tried to re-route and install it both ways, either way I am still getting 14psi. I even tighten the boost controller almost all the way down. I guess its either the boost controller or its MAJOR leak. I was going to try my friends hallman boost controller but it uses bigger vaccum lines and my engine bay was to hot to disconnect the line on the wastegate, maybe nexttime.

 

Hey E.

By-pass the boost controller all togther and run your vaccum line from your pressure source (preferable from the comp cover if you have it tapped) and run the other end straight to the wastegate and WATCH FOR THE SPIKE!!!!!! if it spikes then your boost controller is the suspect. If your wastegate still opens at 14psi, then there you have it---wastegate!

 

Hmm, well my comp cover is not tapped. So basically if I replace the boost controller with a one way tee, it should only run wastegate pressure, which I believe is 14psi any way, I am correct??

 

I dont know if the your particular wastegate pressure is is 14psi. but this is how i would test the system to pin-point your problem. if you post a pic of how the bc is hooked up, maybe we can try something else. I'm already a little biased towards the boost controller being your problem.


BTW....you dont need to cap the two nipple from the factory boost solenoid. I did and took them off and there was no difference.

 

Base boost should be around 1 bar.

Remove the vac line to the WG and plug the line. Take it for a rip and see what kind of boost you make. If its functioning properly, your boost will shoot to the sky BE CAREFUL!!! Let off if you see 20+ psi. If it does do this, then your MBC is the issue.

 

I will definately try that tomorrow. I just little bit more testing on the boost controller and I am almost positive its the problem. The issue is the spring inside the boost controller its no sitting right I think. Jeff from Perrin told me if I am able to blow from one end of the boost controller and feel air coming out of the other side while the its tighet down, that means its not working properly and I am having that problem right, I took it apart a few time but I am not able to sit right. I believe everything else works fine because when I had the Xede control the boost was above 20psi easy. I guess I got to call Perrin tomorrow.

 

garb a hold of a good ole hallman. I bet your itching too see what 20+psi feels like on that turbo.

 

Well the real reason I want a working boost controller because I want to get my car tuned, then I want to feel the full fury of 23psi tuned on the 30R. Anyhow I am having Perrin send me a new boost controller, it will be here by wednesday.

 

Just to try this test, so I can be 110% sure its my MBC. Just like you said the boost spiked to 20psi+ with wastegate capped and I let off right away. Today I should have the new boost controller, hopefully everything will work out.
