!!!! Help 16 f85 x5m

My X5M under load stalls outs

Downpipe and had BM3 stage 2 tune

A little back story driving one day and brake malfunction came up and pedestrian malfunction and couple other warning lights about an hour after car starts to stall out mid traffic have it towed to the stealership obv they saw the tune and blamed the tune and that ecu's were bricked car had cel for no communication with dme 1, took the car to get a second opinion and same thing said both ecu's replaced to be replaced… so okay replaced both DME's and problem still continues….. car idles completely normal no lights nothing.. in neutral you can rev it up no problem but when you put it in gear and then drive it will drive no problem if you drive it very lightly problem comes sometimes when you give extra throttle sometimes it stalls out and all the malfunctions light come back on

Anyone have any problems like this???
