I think you are having boost controller problems you should be able to boost over 22psi on a 15 pound spring. your solenoid might be messed up. do you have the profec-b?

If your running the greddy wastegate you have a 8 pound spring if i'm not mistaking that is what came with my kit then you will prolly have to get a bigger spring then that would fix your problem

If its an 8# spring you may need a stiffer one with the profec as they lack the resolution to make much more than double the spring pressure. If its not the spring try taking off the air filter, I have had air filters cause this problem before, especially the foam filters like the HKS and the Greddy.

You could also be blowing air out of the intake manifold area somewhere and not know it. I run into that fairly often.

Hey Justin, sounds like you have a leak somewhere in the gate or the lines somewhere, OR the boost controller isn't connected properly, check over the install and I bet that's it's something not connected properly or leaking.
