6.0 whiteish smoke on acceleration

[Allyson]

I have a 2006 6.0 with an EGR delete, FICM, injectors, and an SCT Tuner. Any ideas why it smokes when the oil hits 127 degrees? If it has a load it doesn't smoke. My mechanic is tumped too. No codes. But god help you if you're in traffic and have to take off.

Blue is usually oil and unburned fuel sometimes.
