Ka24DET surging idle problem (video)

[Unstock240]

Well My KA-T runs pretty good for the most part. When I drive it for about 30 minutes the idle starts to do this: causing it to die as well from dropping too low. What should I check out? Never did this before turbo, and the bov is recirculated.

How is it tuned?

How is the IACV hooked into IC piping? ECU Temp Sensor been replaced?

Running 8:1fmu stock on 7psi is my tune lol.

the iacv is just straight into the coldpipe? and i have swapped ecu temp a few times.
