First off I am not a diesel tech. But I believe the PCM doesn,t know the heaters plugged in until the starter turns over and the sensors detect an unexpected change in oil and coolant temps/pressures. At which the time the PCM has to readjust fuel to lower emissions. In other words its all about the 6.0 emission control calibration in my opinion.

I've tried with the EGR unplugged and plugged in, no difference. To who ever said to get rid of EGR.
As for the 1-4 seconds, not even! In the winter at 0-20F it hits within one or two revolutions. Runs a little rough for a second or two then smooths out. I figure that's to be expected at 0F. Fast forward, or back up, where it's 60- 70 at night and it cranks and cranks and slowly starts hitting more and more until just as you think the batteries are going to die it's spinning fast enough to let off the starter. Reminds me of pull starting my dads old Cushman. If I plug it in when it's cold, it's hard to start just like it was summer. It is quite annoying.
