    18 sp635 turbo brake

    It’s right after the turbo, it pretty much cuts off the exhaust to build pressure in the cylinders. I believe it’s closing up on you. Does it do it all the time?

    I had a similar problem when my EGR valve went out, but my check engine light was on the whole time. Might want to check there. If you hook up a scanner and check inactive codes, it might lead you to the problem
