Help with Paxton Stalling

[Stepa J]

Hoping someone might have some ideas. 2020 A10 with Paxton kit. Typical set up with FIC1000, BAP, 3.6 pulley, IMRC lockout etc. Unfortunately, I have consistent issues with the car stalling when coasting to stop or sometimes on start up/parked. I've tried two very well known tuners..one being exceptional with service. So I don't think it is the tune. Kit was installed by reputable shop in area and I can not find any potential air leaks or anything out of place. Plugs replaced and gapped per tuner specs. Really at a loss as the car only had few thousand miles on it when supercharged. Any thoughts or ideas are greatly appreciated!
