But problem with your managment is that your ECU wont reconise the fack you chagned the managment and then chuck more or less fuel in, as your air mix maybe different compaired to your old Inlet..
A change of management includes the ecu mate, thats the whole point of the conversion, the fuel is managed by the ecu and controls the fuel dependant on the info from the air temp, coolant temp and map sensor ( which are reading correctly! )
And incase you are wondering, it's not my first conversion, just struggling as the car had a fault before it was fitted
