coolant puking

I originally had this post up as "coolant gulping". My truck looses coolant while pulling my 8000lb trailer up grades ( a gallon is not un-common). I have an 04 with full guages,Airraid intake, MBRP cat back and run a Predator tuner (now for sale after what I read here). My truck just came back from the dealer, and they found no leaks anywhere, and want me to bring the trailer so that they can duplicate the problem. I have not tried pulling the rig without the Predator, but will do so tomorrow to see if it still pukes. The coolant seems to be coming from the res cap. Any thoughts ??

Si, it is El Diablo! Lose the predator forever; however, you may have some stretched head bolts already... Via Con Dios!

More than likely it is puking through the head gaskets under load. Have the dealer do a pressure test of both the EGR Cooler and the Cylinders.
