Common myth. Leaked boost just spills out and hits the turbo, which gives you more boost.
Look at HKS cams for DSMs. They've got 269 or 272 degrees of duration, depending on stage.
Then why are all of the turbo cams for our cars short duration and high lift?
Also the turbo creates so much backpressure, that exhaust can revert back into the cylinder from excessive overlap.
I dont think leaked boost can spool the turbo like you think it can... i think the cons outweigh the pros.
