I've been running Cobb AP Stage 1 map for a couple of months.
I recently noticed that when I start my car in the morning or after work (cold start), the car starts a bit rough for a second or two.
RPM moves up and down rapidly and I can feel the car roughly vibrating.
I tried Stock map (Stage 0) for a few days and the car starts smoothly like it should.
It only happens w/ Stage 1 tune (Version 3.01; 91 Octane w/ normal wastegate).
Here's a quick vid.

I'm just curious whether this is normal. Any suggestions on resolving this would be appreciated.
