Would it be easy to describe or characterize what you have changed for these mods'? I saw you mention Flex-tuned, so I imagine your car is tuned. If you haven't looked already, I might also see if your Virtual Torque tables have been adjusted. It's hard to say not being able to see the tune or a scan, but if you're tuner touched anything air flow related, it could be your VTT idle areas could have moved around. I doubt your mods' might require that, but in the event someone changed them from stock, it could be that's something to look into. Again - I wouldn't think that would be necessary for your list of mods', but I wouldn't know what your tuner did or didn't touch.

VTT will influence idle. A calibrator who helped me said that he liked seeing TMA pull around 10* of timing at idle, just so it's doing it's job, and had enough timing swing to add or pull torque to achieve the desired idle speed. Of course, there needs to be a minimum advance so you don't melt cats and such, but I'm just saying VTT is very important for idle, and if that's not shaped correctly, you can have some naughty behavior.

Also - have your Driver Demand Increasing/Decreasing Immediate/Predicted torque rates been moved around or anything? There's a TUTD function in those, too.
