Default bad tune?

alright i just picked up my new car the other day and ive got something strange going on. when you start the car it idles low then when you take off its real slugish and wont hardly run like its missfiring but after 30 sec. to a min the check engine light will flash then it runs fine, and tonight i had to slip the clutch out while driving just to make it home and after idleing for about 1 min it staightend up again then ran fine. but it does this everytime you start it. it is a h/c/i car with ls1edit, and i have an appiontment to get it tuned but i just was wondering if the tune is the problem.

I would start with the tune. Then, upgrade the pcm.
