Boost Leak Or Jaycar Boost Control Crazy?

[madmoomoo]

Hi folks,

I am getting too much boost at the moment and obviously need to get it sorted out quickly. Here's the setup:

R33 gtst, stock turbo/intercooler, jaycar electronic boost control, just changed some hoses to silicon because of split rubber hose.

I have two boost settings - one about 7psi and the other at about 10. Firstly, I thought the High/low switch for the boost control had died cos the controller is saying that the boost is always on low (according to the hand controller), however, regardless of what setting it is on, if i leave my foot on the pedel, boost goes up over 12psi!

I have tried to check the following:

1) boost solenoid (is clicking away when needed. I played with hand controller to test this)

2) looked for leaks/loose hoses. I can't find any leaks or loose hoses, but I am thinking this might be most likely prob.

3) dodgy soldering job on boost controller - I pulled box apart to check all the soldering, but I couldn't find any suspect bits.

I'm a bit confused by this. At the moment I'm thinking maybe it's the boost controller that's crazy, but I can control the rate of the solenoid manually and it sounds fine, so it doesn't make sense to me.

If anyone has any ideas at all, I'd love some help. I really don't know what to try next.

Thanks.

alls i can think of is the boost controller isnt up to scratch. doesnt sound right. i havnt heard much about the jaycar controllers. a mate of mine had a boost spikeing prob which turned out to be the controller was too far away from the turbos. if u had a leaking hose, 1. ur pressure would be lower. 2. u would hear the hose sucking air. sorry if this isnt much help...
