too high compression?

That EGR has ~10lb spring in it. if it took 5" at around 4 square inches to pull it off (youtube vid) at the low setting. Its tighter now, I got to get another mighty-vac to see where 1500-2000 RPM is on the line from the amplifier to dial in the pintel. Those thermo-valves are interesting....there is second down there for evap, and that one is routed correctly.
