I have a LudeSPeed Stage III and due to some kind of problem, have not be able to get Tom to send me the Vortech Fuel Management Unit. So, I am stuck sourcing it myself.

The FMU comes in several different calibration ratios; 6:1, 8:1, 10:1 and 12:1. Does anybody have any advice on which I would need based on the stage III kit?

Thanks for any help!!

 

I was under the impression I needed it along with the LINK and injectors.
