Yeah...Quick up and down/jumpy throttle, and black smoke, means to much fuel too soon. I realize 52, isn't cold in comparison to 32 or 2, but when compared to operating cylinder temps it is cold.
My first tune from Doug, right after I got my SCT had the same problem, he sent me another, where he defueled it a little at lower throttle positions, and presto, it was much easier to drive when "cold". This is coming from my experience solely...talk to Eric, and I am sure he can send you some adjusted files that take care of the problem.
