On the greddy kit, I've had nothing but problems with it overboosting. It's been getting worse lately. Kpro is saving my motor but it's shooting up past 7psi (upwards of 15) very fast even with quarter throttle.

Sometimes it will work fine, I thought I had fixed it but it worked for a week. I replaced vacuum lines, even tried the test to see if the actuator opens at 7psi with an air compressor and it does... So I'm quite confused

I recently switched the actuator arm and boost gauge on it's own vac*** block from the pcv intake manifold port (installed a catch can) to see if that would help in any way, but no such luck.

Can anyone tell me a potential issue that would cause this, and a way to fix it? I cant pass anyone on the highway without hitting my 12psi boost protection wall.
