Exactly...no point in spending $100 for an FMU, $100 for a fuel pump, missing link, check valves, afc, tuning, etc...just spend a few extra hundred and do it right. Thats not to say you cant make power on an FMU setup, I just dont see why anyone would want to anymore.
Sounds like a pain in the ass for a T3 setup. Buy a used greddy kit and save yourself some time if thats what you want.
