So ive had this problem where the vehicle would cut off for a quick second when accelerating from 1st to second gear(issue happens in 2nd gear) from a stop, had this issue happen for a while when the vehicle was on a cobb tune. recently changed to ecutek with new ecm and tcm tune which made the car shift much better and made the issue seemingly go away. issue would seem to come back once in a blue moon but after that, would not happen again for a while. noticed the bottom coupling for my BOV pipings were loose and thought it was related to a vacuum leak, after readjusting the couplers flush and tightening the fasteners, issue appeared to go away for a while but had recently came back in the next day or so, very subtle but rarely does it again. vehicle is a 2016 and has about 33k miles and already had one diff and trans service done. In the video you can see the issue happens in 2nd gear when the bovs release air while still accelerating.
