Mike...I'm missing something simple here, I think.
Given your statement above, in the bolded part, how is it necessarily true that a shift is taking place? If you are 100% throttle, then wouldn't simply lifting off to slow down (not shift) also mean a "rate of change in RPM AND the gas pedal value dropping"?
What is stopping the JB3 from saying "oh, the car is shifting, I'd better maintain boost" when the driver is simply lifting off of the throttle to slow down. I must be missing something. I would think it would be quite detrimental to have the car keep boosting after the driver gets off the gas, when he just wants to slow down.
Thanks
