right here's the scenario..

what would happen if i was to take a chip which is written for a standard engine with a t34.63 and stuck it on a car with a standard engine but with a t34.55?

how would this affect the running of my car?

 

just need to get the fueling checked, its not ideal but it would work assuming everything else is the same.

it would probably overfuel

 

You WILL need a remap, the exhaust housing is crucial to the calibration.
