with such rough information you cannot adjust a MAF.
You even cannot see which side of the 6 cylinders consumes what quantity.
If you drive only with one side you will have a very high fuel consumption indication even if it is not there for real.
It will be very high with about > 30 liters/hour if you drive on the right side, and if you drive only with left side connected it will show 3.5 liters per hour.
If you want to run on one side only, just pull the corresponding main relay which switches off the pump.
In case of my 1988 the relay for the lambda control is only connected to the right side.
If you pull the main relay on the left side, you can drive with 6 cylinders.
