FMU or Super FMU??

My FMU on my Vortech needs to be replaced and was considering switching over to the super FMU. Has anyone done this and do the adjustments make a big difference?

What is a super FMU? The stock FMU is no more than a vacuum operated valve that allows fuel flow to the Aux Fuel pump to supply the injectors with sufficient fuel under boost..Does the super FMU allow more fuel flow to the Aux fuel pump?

The stock FMU increases the fuel preasure by 8 to 1 . 8lb's for every 1psi of boost . If you changed out the injectors , you may want it. But other than that , I dont see why your would need it
