Boost not increasing over WG pressure

shadow85

My latest dilema, is 2-fold:

1. Boost rises and hovers around 7.5 Psi no matter what settings I punch into the EBC, in other words I cannot increase it past the WG pressure of 7.5 Psi?

2. Even though the boost only wants to stay at 7.5 Psi, there is a spike in the middle of the boost curve where it jumps by1-2 PSI as in the graph below:




Does anyone know why I cannot increase the boost past the WG pressure.
I have tried SET: 10%, 15%, 25%, 35%, even tried 40% but boost is not increasing past 7.5 Psi, but still spikes to 9.5 Psi.
Its like the EBC is working only as a boost gauge!

I have AAM TT Stage 1 kit

Any ideas whats going on?
