The car is all stock except for an exhaust behind the cat, NGK Racing spark plugs, Delicious Tuning ignition coils, and of course the Edelbrock supercharger. Currently the ECU has the "CARB" tune that Edelbrock includes with their supercharger kit. My main concern is to know if it is running rich or lean (you said it was running rich last time) as I am most concerned about the longevity of the engine. Also, when I push in the clutch the idle will go up to 2k RPM for a few seconds then settle back down and sometimes bounce around a little. I would like to know what is causing this. Lastly, at low RPM, it does seem to be a little rough sometimes(3k RPM and below), before it gets into the power range (4k RPM plus). Its not bad, so I wonder, is that the nature of the Edelbrock CARB tune? , I am very happy with the performance currently, so I am most interested in a long lasting, reliable engine. I have included 2 examples, the first one (indicated by the time stamp) starts with the engine cold and drives until warm up. The second example is with the engine warm. Both are trying to share examples of all the concerns I described above.
