I can't remember but the overboost code was thrown so 22 psi or more. All at close to sea level and over 80º. I have no experience with a 185 or the Crossover manifolds. I'm still on the fence considering the Crossovers.

Me too Les. Someone brought up a good point about adding crossovers and lowering boost in another thread. The crossovers increase air flow but lower boost. Well, our ecu can't measure airflow. It calculates it using boost pressure and throttle position. Less boost equals less fuel. Just something to chew on....
