ah cool, i didnt know how much pressure off throttle there.

makes loads of sense now

how/why is it less damaging than normal ALS? heard things like that, and it creates less heat?

but then, if you believe that forced induction tuning book, Ferrari F1 first used it, but had to stop and revert back to normal ALS as the EGR setup was more heat, not less?
but there a few "facts" in that book i know are wrong, so that may be too.
