I have a P2457 code now for 2 months as I’m waiting for a EGR actuator that’s been on back order from my dealer . The truck today was noticeably gutless and getting worse. Flat highway no wind not pulling truck had trouble going 110 km hour. I could barely pass people. Sometimes it rips a bit sometimes it barely responds if u mash pedal to floor at highway speed. Is this normal?

Does not sound right, mine will hold 110 easily on cruise without dropping gears, If you are foot driving it will drop to 8th sometimes but i have never had to floor it to pass. The roads over here are far from flat.

No codes on dash other than occasionally a P2457 comes up dpf pressure differential
