Default 95 mustang stumbles

For the last month I've been trying to diagnose the problem with my 95 Mustang GT. You guys have provided me with great help. Under normal driving, the car pulses. It is hard to explain this. Once I get into the throttle the car breaks up bad, starving for fuel. I have replaced fuel pump(255), fuel filter, cleaned MAF, replaced head gaskets(blew one), added MSD coil, ignition wires, plugs(champion 2 ranges colder .32 gap), distributor, cap n rotor, ignition control module, removed FMU(then put it back), and more. I am starting to wonder if I may have a leaky injector, as a leaky noise is coming out from the injector area. They are 30lb'ers and with the SC it could have done them in. The symptoms of failing injectors seem to match what is going on with my car, but I am just not sure. Any help would be greatly appreciated. Mods in sig.Thanks

you should get a wideband O2... I have a feeling that you are running a bit too lean. FMU'
s are not a very good way to tune for boost
