Hey man the MF2 will work perfect for your app plus you already have it no more money to spend. You can fine tune it pretty well but it won't be as good as a stand alone but IMO it will be better than a FMU. But if you want simplicity sel teh MF2 and get a vortec 12:1 FMU and you will be fine also....you will basically have a spool kit then.
