How in the heck did I miss the post about belt slippage?
It's interesting, when I first got Bill's custom tunes and had a reason to do a WOT shift (during a passing maneuver) I heard the squeak and thought it was something in the transmission, not the serpentine belt in the engine!
I had never heard this squeak using the canned tunes that were in the Edge before it was upgraded to a Gryphon.
At first, I was kind of worried, but then decided maybe things were OK (since Bill wrote the tune and "he MUST know what he was doing").
