I now think ive ruled out a problem with the boost controller, unless it is the soleniod stuck in the same position.

 

Even if i turn off the boost controller off all together, its still pumping out abou 15 psi at wide open throttle, having said that if i put the controller on the hi setting it can hit max of 16psi before it alarms and backs off.

 

Fookin thing is doing my head in, is there a simple method of unplumbing the controller and putting it back to stock, to rule the controller out altogether.

 

Its a greddy profec e01 if that helps.

 

Any ideas appreciated on causes of this or ways to test the wastegates etc. :headvswal

Come over mine on Sunday bud!

 

We'll see if we can sort it :)

First ive read of it. You havent got boost jets in the pipes have u ?

Nope, was stock till the profec was put in, has ran great for 6 months, now its just gone mad on boost.

 

Used to run a steady 5.5 to 7 psi stock with the controller off, but now it hits 15.

You reckon you can get hold of your soleniod off your tt for sunday mate so we can try that?

Cant see a prob buddy, i'll try to get it tomorrow, if not Sunday before you come over.

Hi B19rks,

 

Just looking at this thread from earlier in the year about overboosting and I think I have an identical situation.

 

I have a Profe b spec 2 controller and I am experiencing the same problems you had, it was working fine for 8 months now it is overboosting like a maniac.

 

I think it may be sticky actuators/wastegates but I was wondering if you found out what was causing your issues and how you sorted them out.

 

Your feedback would be greatly appreciated.

 

Thanks, Mike...
