They will be looking for a CEL or monitors that are not showing in run condition, that's it. A tune will adjust your fuel trims, and can also be used to turn "off" certain things (like the CEL for down stream O2 sensors), adjust your fan on/off temps, etc...

ight thanks but what about my SRT question or the driving cycle...

Ok, I can only assume by "incomplete"' you mean that the dealer told you they are showing a monitor that is not showing a "ready" or "run". This can, as any CEL can, go away after a certain number of driving cycles if the ECM doesn't see an issue over time. If it's related to a mod you made to the O2 sensors or cats, then it will probably not just go away, and will require a modification by a tuner.

I had this issue with my last Z06 after a LTH, HFC and Katach 110 cam install. Had my local LS tuner take care of it with HPTuners software. No emissions issues.....lumpy idle and all.��
