Default Turbo LTx with LS P CM (0411) Swap - High idle upon hot restart

To start off, I'm far from an expert tuner but I've been trying to get a reasonable tune setup for a friends 2nd gen TA with a turbocharged LTx 355. The car will start up and idle perfectly when cold but upon a hot restart, the idle will go to 1500 or so. I'll messed with all that I know to tweak but still can't get that hot start high idle under control. I've played with the timing and fuel but nothing seems to work. I must be missing something (hopefully obvious).

Attached is the file for reference. Any help would be greatly appreciated.

add a log.

I would suspect its an airflow issue.

Default

does the iac valve respond correctly when manually controlling it using hpt?
