Sorry...I usually associate this site as a tuning site and not a "my car doesn't run right, should I change my spark plugs, cap, rotor, wires...?" With that said, make sure everything is running to spec before diving into the tune. I do want to share that I have a super ram on a L98 with a cam and aftermarket injectors. After dialing in the idle cruise BLMs, I did notice that the engine takes a few more extra revolutions then what I think is necessary so I modified the above^^^suggested. Long crank times can be associated with a bad fuel pump relay something to check as well.
