Issue with starting air compressor

Series 60 / 6063HK33 - hard starting with air compressor load at cranking.The best applicable calibration to use for these S60 Air compressor drill rigs where they don't allow the air compressor to unload at engine crank is below. This 550hp calibration - 06N04M7307 has additional "start table fuelling" to overcome the load air compressors can apply at initial cold start up / cranking etc..
