Rapidly Flucuating boost

I am all out of ideas with this one. So here it is guys........


Having a problem with rapidly flucuating boost. For example, If the boost is set to around 35, the boost will actually flucuate up and down 4 -5 pounds, sometimes more. In a 3rd gear pull from lets say 4k to redline, from the second it builds 35 psi it will flucuate 40-50 times in a matter of around 4 seconds. I have tried to fix the problem by putting another spring in the WG, it now has the big green and small green. And also switch boost controllers, I now have the new Buschur inline. None of these fixed the problem. No boost leaks, car pulls good considering its probably varying about 60 hp 40 times in a pull which is sligthly noticable. A/F's are fine, I have no more theorys left.

Thanks for the help guys

Forgot to mention one thing, Has anyone had a problem with a Tial BOV leaking? I have never had a problem with one, but anything is possible.
