I've noticed maybe 5 times in the year I've owned my car it will seemingly lose all turbo boost while I'm driving it. Usually happens on hotter days at highway speeds, but it's happened on cooler days as well. My boost gauge on the torque app shows 3psi at full throttle, making it very hard for the car to maintain freeway speeds let alone pass or merge. Stopping the car and turning it off then back on resolves the issue.
What at causes this? Should I be concerned? The car is a 2014 1.4 with a trifecta tune and intake resonator delete.
