I have the Diablo with an automatic and I've been pretty happy with Bamachips' tune, though I haven't yet had the chance to track-test it.
One thing that will happen, when rolling about 60 or so, I can floor it and the car will take off nicely but when it upshifts around 83-85, it will actually trip the TCS ( I get that traction control active message ) and the tires slightly bark.
