Moose,
I forget exactly what Piers does, but they claim a 200 degree drop. If I remember right they put in better bearings and machine out the compressor side to accept a diffrent wheel.
FJ,
There is a diffrence in the lower RPM's, it wakes up earlier, but not by any great leaps or bounds. It does make it better than stock, but it is hard to benchmark it since I have never owned diffrent pickup. I seem to get about 1mpg better, if I can keep my foot out of it.
