I megasquirted my 4.5 a little over a year ago. I will say my megasquirt is far better to drive than the old d-jet. No knocking the d-jet because I think it was phenomenal for its day, but this is turn the key and get consistent running regardless of the temperature or weather.

I did the entire fuel and ignition. As with most things, megasquirt will only be as good as the person doing it. You can find a lot of people bad mouth it and then you see the rats nest of wires they have twisted together.

I spent $1,243.03 and that was MS3X with a harness, WB O2, injectors, fuel rail, trigger wheel and sensor, coils, new TPS, IAC valve, air and coolant temp sensors, all new connectors and loom.
