Not really... usually this problem is due to AFM overshoot on deceleration or BOV venting air and not being metered

Been posted on here a few times (search for 'reversion') but basically on decel reverse airflow goes through the AFM and gets measured as incoming air. This causes a big spike in load reading. ECU sees the big load reading and injects a ton of fuel causing the stall

Using plumback BOV going back into the turbo (away from AFM) usually fixes this. Log of the issue when it occurs will confirm this for us
