massflo fuel injection

Hi i have a 433Ci engine which is supercharged and runs a massflo fuel injection system.The car is a Eleanor built by Jason at Classic Recreations.I have done a lot of upgrades and these include changing the exhaust system ,extractors and upgrading the intercooler and fuel pump.These upgrades have improved boost from 17 pounds to 20 pounds and this is without boosting the supercharger .The problem i have is, we have put the car on the dyno and the fueling is way out.Fueling is far to rich at the low rpm and leans out dangerously at high rpm.
I am in Australia and we don't use this massflo system here as we use more advanced computers that can allow you to tune the car and even to have traction control functions.I can not get any help here on the massflo as nobody here uses this system.I have been told that a PMS piggyback system may work,which allows you to tune the fueling.I have spent enough on the car and want to avoid the expense of changing the injection system if i can.Can anybody tell me if a PMS piggyback will work with a massflo fuel injection system?.Thanks
 
Massflo uses a standard 5.0L Mustang EEC-IV computer, as far as I know. I've seen several people use a Tweecer RT or a Moates Quarterhorse with the Massflo, so a PMS should work too, but I'd rather have a Moates. The Moates unit offers very precise control over the ECU, can tune on the fly, datalog anything and everything and the software is more capable than a Tweecer.

The PMS is supposed to be much easier to use (just tell it what you want and it will do it for you) but that approach sort of scares me.
