First off, your fuel trims pull 10% immediately after start up. That should be your first indication right there. Second, you're not logging your IAC, so no telling where it is, and if it needs to be open more on start up, or if it's even right when warmed up fully.

Surge is almost always too much fuel. Need to dial in the VE and MAF. Then you need to adjust the OL/EQ table to get the open loop fueling correct.
