Okay, it seems I have a boost leak after putting in the new diverter valves. At first I thought the install was messed up but I rechecked everything and it is good and tight. I also put in new sealing rings on the lower boost hoses to the intercooler as the drivers side one was removed for the install and was coated in oil. The o-ring did look a little worn but even after replacing it I still have the error code under high boost. My theory is that with the new EVOMSit software and diverter valves (the old valves would not hold full boost) once the engine saw the higher boost it developed a leak somewhere.

What is the best way to troubleshoot this? I checked the diagram for the boost hose system and it has an unbelievable amount of o-rings... would hate to have to take the whole thing apart to replace them all.
