Not enough people have tried it, but the engine break strength is adjustable through custom tuning. Because of this, one could re-adjust the ecm to compensate for it fairly easily I would think.

The other question is will the engine brake even work correctly at all?


For those who read this and think "it can be made stronger?" -- Strengthening above the factory settings it is NOT advisable. Too easy to drop a valve and I have seen many people do it and cause head damage. It is a common mistake that crappy big-box tuners do (and their copy-cats) that helps to destroy engines.
