May be able to help some, but I need to see a datalog too. How many lbs/hr of fuel are you idling at? Did you check the timing before doing anything else? I pull all the plugs out, unplug the fuel injector harness, and crank it over to make sure the cranking timing matches between what you see with the timing light and what the ECM is set for (in System Paramaters / Ignition Paramaters / Cranking Timing).

[email protected] is my email address.

I answered in the supercharged section a little more in depth but you need to up your crank to run rpm to get the cranking fuel table to respond.
