Will it damage anything to not get the reflash?

I have an 04 F550 with the 6.0. It had a COMPLETE engine assembly put in it in late 05. It has not been reflashed to the inductive heating flash since. The truck is completely stock and ever since the temps went into the teens here it does not like mornings so much. It starts harder and seems like it wants to chug and lope for a bit. If I take off driving before at least about 5 min idling when it is stone cold in the morning it is sluggish feels like it is surging and does not want to go. If I let it idle for 5 min then it is fine. Throughout the rest of the day it is fine. Is it hard on parts to operate it like this or is it just inconvienent? I do not mind letting it warm up if that is all it needs but do not want to damage anything if it is unhealty for it and will spend the 100 bucks.Thanks JJ

Switch to a 5w40 synthetic. That should take care of the issue. 6.0's hate rotella for some reason

If it were me I would get the reflash and let it warm up for a bit. Everything likes to work a little more efficiently when it's warmer. Besides, who wants to get into a cold truck?

I had FICM issues and they replaced that and reflashed. I think the truck runs much better. Power seems the same and it seems to run more efficiently. I would do it all over again if I had to.

Check the FICM volts to rule that out, switch to 5w40 synthetic and get the latest flash.

Dealer replaced FICM and uploaded latest flash. Last oil change I switched to 5w40 rotella synthetic!
