Just load a tuned SF file in Delta and then load the stock file and mark changes. You will notice where we made changes and see what you might do to make more power. There is alot of power left over a straight SF file.

That's how I learned... Sniper did all the hard work for us.... it's pretty different than the 7.3 stuff. and it looks like ford put some hard fuel limits in there that take some thinking to get around..... there isn't a pulsewidth table like on the 7.3 it's amazing how much airflow the stock turbo supports. the 7.3 needs a turbo upgrade to even touch what the 6 liter can do stock.

There is a TSB for the coolant peuking. It is usually the EGR cooler or head gaskets.
Heres what I do. With the truck @ idle, cold engine, remove the cap and put your hand over the Degass bottle. If it rapidly builds pressure it is most likely the EGR cooler.
If it doesn't, install an inline pressure gauge in the sys. and monitor the press on a few WOT/full boost runs. You will see a rapid rise on press when it starts to pull hard if the head gaskets are blown. Blown head gaskets usually wont leak coolant, only compression.
This is common if overboosting.
There is gasket/stud kits available to resolve this issue.
I am a FORD Tech and fix these on a regular basis.

Does that mean Ford is endorsing using aftermarket head studs now as a warranty fix? The torque-to-yield factory bolts are too stretchy for this applicaion IMO.....

The way I see it you can A: remove all your aftermarket stuff, bring it to the dealer and have them fix with stock parts under the 5/100k powertrain warrenty. or B: redo it yourself with better parts and boost away!!! Ford is still using the stock gaskets and bolts and the bolts suck! They actually feel looser on the last 90deg turn.

Alot of the dealers will actually work with you and install the aftermarket studs if you purchase them and bring them in with the truck for warranty... but some aren't so friendly....

one trend i have noticed is the oil cooler, if the oil cooler is restricted they will run hot and puke. if the engine oil temp is not within 25deg of the water temp the oil cooer needs replaced. seen several 6.0"s puke and it not be the headgaskets.
