I called Boundary yesterday and they do recommend shimming +2 for the VQ platform. If I would have been more patient and done more research I would have figured that out before buttoning the engine up last year. Lessons learned. I purchased a low mileage replacement engine yesterday as well as the full pump assembly from Boundary. This will give me a fresh(er) motor to track with and I’ll keep the current engine on a stand to tinker on.
