duration leaks boost thru overlap. You can dial out the overlap but that will throw other things out of wack, such as valves staying open too long.
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.
