LH 2.4 fuel cut dodging...

I am running an MF2 with 3 injectors in the intercooler pipe in addition to the stock fuel system on my 91 SPG. I have a 270 ohm resistor in the orange wire to avoid the fuel cut, but I would like to do this more elegantly and make the car run a little better. Does anyone know how much current the orange wire carries? My DMM does not measure current, I was hoping someone could answer this for me. I plan to install a zener diode in the wire to prevent the ECU from seeing more than 4.5ish volts from the AMM.
I dynoed at 202whp on 16psi. It seems I have a boost leak somewhere, my wastegate actuator spring is not up to the task, or both. The fuel system is easily up to the task and I have yet to find the limit of the ignition (MSD 6AL is on the to-do list). I have the Apex AVC-R EBC maxed out at 2bar but rarely does the car make more than half of the target setting.
It feels pretty good when it pulls hard but 200hp is not nearly enough for my 2000rpm-wide powerband.
Be very careful about fuel hose selection. I narrowly avoided a carbeque.
