I have a international pro star 2018 with a Cummins ISX went to Cummins many times for noise fuel and power from the day I got this unit brand new Freind told me to check with GB Edmonton they did my whole engine under warranty solved my fuel issue I recommend if you want it done right then these are the people to trust Dealerships and CUMMINS have given me just a run around for last two years Thanks to Sunny and his team it is like a new truck now .
