    ummmm wtf....the fmu is not your problem if its flooding before starting, an fmu is mechanical (meaning it has no electrical impulses that tells it when to turn on, so its not even regulating fuel pressure before starting the car) and only raises the fuel pressure when it sees boost, meaning it doesnt kick in until boost kicks in, fuel pressure will stay stock at idle or out of boost, so if you have a 12:1 disk it will raise the fuel pressure 12psi for every 1psi of boost it sees, but will not raise pressure before seeing boost, if it did you car would run like balls out of boost running extremely rich

    edit: what kind of eclipse do you have? (is it a gs, rs, gs-t, gs-x?) im trying to figure out why you have an fmu to begin with, is it a n/a eclipse thats been turboed or something? theres no need for a fmu if its a 4g63t the ecu takes care of that problem until a certain point and then you can either go dsmlink, safc, or a nice stand alone, and you say its using a fmu but was tuned by batlground, what kind of tuning did they do, to my knowledge you cant use a fmu and say a safc, dsm link, etc together...b/c an fmu does mechanically what a safc, etc does electronically but with virtually no tunability
