Wow very nicely and interesting read. I only wish this was found out a bit earlier. Although im not sure if what Im thinking is closely related.

My car would do the same thing...at wide open throttle the BAS/ESP light would come on and it would act as if it had nothing in it.

But the fix was replacing the whole supercharger assembly. I guess that wasn't even needed if the problem was the same. Im not that mechanically inclined so Im not sure if it is or not.
