i took the car to r/r cause when the car is ticking over theres a strong smell out the exhaust. when it went on th rollers the guy told me the car is running rich on idle and midrange but ok high up the revs. the fuel pump wasnt working properly as it was weakening when it was made to work hard. so pump was changed to a 044 and i was told to get a new wiring kit for the pump i havent been back to r/r yet. spec is T4 greys bd10s i/c exhaust and your chip was told by last owner its stg 3.
