Oh, NO NEW GIZMO other than the Merlin. Interesting though that you are seeing a measureable degradation with that engine though. I wish I could say it has to do with that "Merlin Whine" that is one wierd sound isn't it? That being said, after running the Merlin around 5 or 6 times thus far, the throttle response is very fast and the temps and thrust are AMAZING.
