It is no big deal but needs to be fixed. You could look at it this way, your truck is working so well that the turbo is making more boost than the tuner expected at 1700rpm. Your truck can’t swallow all the airflow and boost and is letting some out through the intake. The limitation is because of the compressor design, you end up having a PR
that is above and to the left of the surge line if you look at the map. It will take your tuner longer to read your request than it will for them to make some slight timing or possibly fuel adjustments that keep your boost down a little bit and inside map. You shouldn’t have any additional problems and your not going to notice anything different other than your boost may be a little lower in the 1700 rpm range. Good luck, Tom J.
