Does the TPS sensor go by any other names..... i know this sensor regulates fuel cut but does it do anything else?

The bottom one, I'm sure, it is turbo pressure sensor.
Like Bryan said, everytime I heard TPS, I always think the Throttle Position Sensor. I'd rather call it MAP sensor.

Appart from these 2 functions it serves no other purpose. There is no pressure sensor based fuel/ignition corrections on an st185 ECU.
If you electronically disconnect it from your engine (ie you cut the PIM wire, unplug the sensor wiring harness etc.) the ecu will begin to calculate fuel cut based on the signal from your AFM & throttle position, and when you hit airflow based fuel cut you have to reset your ECU (by pulling a battery terminal). Basically dont do it.
It will also (by some means which i have yet to establish) pull ignition timing much more readily with the sensor electronically disconnected.
If you want to kill fuel cut, the best way to do is is to unplug the vacuum line from the TPS, and leave everything as it is. This is 100% effective with zero side effects (except for complete absence of pressure related fuel cut)

The head is different and i assume that makes a lot of other things different but when something as large a part of the engine as the block is the exact same. Then the engines are pretty similar when we are talking about all internal combustion engines.
