Lower CR will reduce overall thermal efficiency lowering the overall Volumetric efficiency. torque output is a result of VE, you are basically doing the same thing cams do. Cam+ lower CR= drastic dymanic CR change. Power band will move.
If your looking for torque down low you might want to pick your turbo carefully. something that can flow good in the low PR without surging, but will still be able to flow good as PR increases. Port work will also help as it increases VE.
