Surging on accel when cold

Truck is surging when cold only on acceleration unless it has been running for 20-30 mins. Has no problems starting. Doesnt matter if its hot or cold outside although its worse when cold. I pulled EBP sensor and tube is not clogged, I found nothing when I took turbo apart and no change with egr disconnected. I am ase master with L1 but dont have a ton of diesel experioence and need some info on which way to go. I am able to use scanner with data stream if I knew what to look for.
