OK, It was just tuned. Ive been going back and forth with the tuner working out street bugs, so Ill have it fixed, I was just curious what actually caused it.

Cold start / afterstart enrichment can be excessive and
so can the EQ (OLFA) table especially after a cam puts
you at higher than stock idle MAP. You should be able
to tell by comparing commanded EQ against these to
see who's in charge. I had to skinny down all of them
after my cam swap. But go to far and you may get
harder starting. If the surge is still there after 10
seconds into cold start go for the EQ (vs ECT vs MAP)
first. If it's only initial and goes away quick, probably
the after-start enrichment.
