Your FI injection computer needs to be cleared of data it has learned over recent time to adapt to running your engine under past conditions.It needs to be cleared and then relearn the new conditions to operate under the new conditions.With the new 3.0 bar higer preasure regulator the timed injection pluses need to be shorten to run the engine,over the longer pulses the 2.5 bar lower preasure regulator reguired.The engine controls you have should very easily adapt to the new condition after the computer is cleared of the old data.
If you know your radio code just pull the + battery cable for 1/2 an hour.If not you will need to pull the FI ECU and unplug it fot 1/2 an hour(it's under the flase bulkhead cover)right in front of the driver.Good luck.
