Help p1335

[farmall6]

Check engine light came on yesterday and plugged in my sct and got a p1335 code. I cleared it and went to drive into work which is all interstates. Tried to get up to 65 and it seemed luggish, barely made it up to 55. Cpl hills seemed like it had a hard time climbing. Need help, btw its a 08 6.4

Bad egr valve. Either take it to ford to have it replaced or delete it and get some tuning.
