Message air/fuel ratio or poor electrical connections.

Stalling due to a/f issues may be separated into two categories depending on your setup, too rich or too lean with single pop or a large a/f ratio difference between banks when using a dual pop setup with a single MAF.

I dealt with stalling when pressing the clutch for over 2 years with my dual pop/JWT chip setup. I tried the duct tape and the flower pot tricks, both to no avail. I also rigged an air balance hose between driver and passenger side boost hoses, that did absolutely nothing. I also tried various restrictors in the hose feeding the AIA valve, nothing!

The ONLY fix was to pull all the extra duct tape, flower pot, hoses and restrictors and set up dual MAFs and take advantage of the DecAir feature on the AFC.

It worked perfectly (after considerable fiddling with the AFC), so clearly my issue was an uneven a/f ratio between cylinder banks amplified by the fact that BOVs were throwing off the MAF readings.
