another lly overheating question
 

So I do belive I have a blown head gasket bc I have alot of pressure in the upper rad hose but it starts really ruff any input on that

what do you mean by rough? hard to start or runs bad when it first starts up?

ya starting is real ruff like a ford and runns shitty then the white smoke blows out

that sounds like water in the cylinder when its first starting up does it clear up after it runs for a few seconds?

ya it clears up then builds alot of pressure in the top rad tube i order all the gaskets and arp studs just wondering so off this subject my buddys got a 04 cummins and he wants a efi live tune like mine witch i sent my ecm off to have it tuned can u do that for his since ur a dodge dude

right now i do not have the bench harness for the cummins ecm

your best best is to purchase a V2 from a vendor it comes with two licences as well, but they are going up to 899 now there is going to be a price increase on them.

or an autocal

they have autocal release for cummins?

tuning isn't available for the 03-05 cummins yet, its only ready for the 06-07

It does sound like you have blown head gaskets as well
