    Its been deleted by the previous owner. Maybe it lost some engine braking power when they programmed the ecm. You know how it can be fixed? Maybe have it tuned again?

    I have Volvo 2011 670 with cummins isx 500. I delete the egr and dpf crap from my truck and since then i can tell that my engine brake is weaker since that day and when i activate my engine brake is kinda late 1sec it’s not braking right away, but i don’t think it’s that big of the deal(I think this delete makes the engine brake weak.)

I’m having an issue with my Jake as well I already changed the turbo 3 times 2 different Vogt valves and the Jake only works at times when it works is fine like any other truck I’ve driven but when it doesn’t is just like I’m using it on low setting no hold at all
