i have a 408 with cnc ported 6.0L heads, vic jr. intake, 60lb injectors, 85mm tb, stock coils, and procharger with 12lbs of boost. my problem is the passenger side cylinders seem to be running fine but driver side is not. i pulled plugs on the drivers side and 2 cylinders look like new and 2 cylinders are black and the passenger side plugs look fine and are all the same color. ive checked all the wiring and have found nothing wrong from what i can tell

 

clean injectors

 

check spark, fuel and compression.

 

What are your plug gapped at? I have seen blower car's blow out the spark with aggressive pullies.

 

Just a thought maybe o2sensor
