Boost Stability

[Race__24]

Ok, I have recently installed a Blitz SBC I-D boost controller and now the boost won't stay below 10PSI at high RPM, even with the controller turned off.

Any ideas?

I plummed a hose straight from the IC piping to the actuator and boost stayed at 8PSI. Re-plummed the controller and it still creaps up over 10PSI. I've double checked the connections to the controller etc.

The controller restricts some air as it passes through(when turned off) but i wouldn't think it's enough to cause this.

I'm stumped as to what it is so i thought i'd throw it out there and see if anyone else has had the same problem.

Some ideas that i've had are:

A hole in the hose between the boost controller and the actuator

faulty actuator

faulty boost controller

But basically i have no idea!

If anyone can help it would be greatly appreciated

Thanks
