So i just a question/ couple questions on a Mack rack. I know it's supposed to add 2mm or something in full fuel rack travel equating to like 20cc of fuel or whatever it may be. What my question is, does any other rack limiting mod trump the Mack rack. Like having not a 0/100 plate or having the plate not full forward. Because I thought the fuel plate was the rack stop so unless the plate full forward does the Mack rack not take effect.

 

correct to take full advantage of the mack rack cap the afc and fuel plate will have to be modified
