Surging

Anyone else have a surge when their truck is cold, around 160. Mine feels like it's bucking/ surging bad sometimes. It did it even without a tune. The fuel filter is only a month old and it's a Napa (Wix). I can't figure if it's the turbo, the programing, or bad fuel.

06 Sierra 2500 4wd lb. Predator, S&B, MBRP duals-no cat, Quadzilla gauges, Allison Jr., Riderite air bags, PPE Tie rod sleeves, egr plate / finger stick. 02 Chevy 3500 8.1L 4wd dump 9' Fisher mm2, sander. 03 Kubota L4630. 80'S or 90's Komatsu pc50. 89 d250 5.9 which may someday go into something.:

if the ambient temp. is below 32 degrees the tranny will hold a longer shift pattern to help warm the engine which warms the cab quicker.

programming likely will fix it.

take this into consideration, the fuel is a lot thicker when cold and sometimes the fuel pressure regulator has a hard time keeping steady pressure

Shouldn't be much of a problem with winter blend.
