the correct setting for my ser 1 i believe was 33-41 mV. i had one out of adjustment, much like ur describing in ur "mod" and once the pedal was to the floor, the throttle percent went through 100% and then dropped to 0%. and the engine would die if i kept foot on the pedal.
so from my experiance, when you go past the full setting, it went to zero.
ur tps is one of the most critical sensors used to time ur spark with ur fuel delivery.(well at least on ser1) i would imagine that to be true on ser 2 as well.
