No that is completely normal it was just closing to help the engine warm up faster. I wanna say when I was in Maine anything less then 60* it would actuate. I love the way it sounds. It never fails though someone always asks whats the matter with your truck.

First time I showed that tune to a couple of co workers, they thought my truck was gonna blow up or something, they all started backing away like something awful was gonna go down

Sounds like normal operation to me. Check out page 4 of the attached link. It has some specific info regarding the EBPV. Air temp should be below 50 degrees and oil temp below 70 degrees and then it might close. Will even happen while driving under certain conditions.

I then explained what was happening and how it can be used as an exhaust brake with some simple mods or custom tune. They had to cough up about $2k to accomplish the same basic thing that Ford gives you for free.

Meanwhile, someone clever figured out that it can also be used as an engine brake by wiring up a manual control switch.
If you have a manual trans then you are good to go.
If you have an automatic then you also need a way to lock your torque convertor. It can be accomplished with a switch and relay.
If you don't want to mess with wires and plan on getting some custom tunes, then you can purchase a DP Tuner with a decel tune that takes care of that for you. Not all custom tuners offer a tune that operates the EBPV and TC so you will have to check with them prior to choosing a tuner.

The EBPV used as an exhaust brake makes a whoosing noise. Sorta like letting the air out of 100 tires at once. Not very impressive sounding but sure is comforting to hear while hauling 24k lbs down a steep mountain.
