Rough engine idling question

I just had a LS3 418 CI Stroker motor installed in my 00 Camaro-All forged Steel internals etc. It was tuned on a dyno at the builder's shop in Texas. The car is not being driven now b/c it still needs to be finished- body etc.
My question;when I initially start up the car it idles very low and irratic when i put in drive (it's an automatic) it sometimes stalls out.
Cam specs- Comp Cams XHP custom cam.

Duration @.050 238/246
Lift .624/.624
LSA 115

But after letting it run awhile the idle smooths out to around 800 rpm and no issues. (?) seems like Cam surge if that is the correct term. Or is the computer trying to relearn the engine ( I dunno-just guessing). I thought a dyno tune is supposed to prevent this????

Any information would be appreciated-I'm thinking of sending the computer back to builder to be reflashed.
THANKS TO ALL IN ADVANCE

Typical tuning issue. Should be an easy fix for any competent tuner.

Get the link below to your tuner. Tell him to read it line for line first...then go back and apply it in the same order provided. ENJOY!

Thank you-I believe it was programmed on HP Software
