High EGT with stock F350 and bullydog tuner

[elkrause]

Hi all,
This weekend I was on the road for a 600 mile road trip for work. The first 300 miles went just fine. Had the cruise set at 65 and the bully dog triple dog GT tuner set on the no power mode. Once I reached my destination I I drove around maybe 10 miles in a few days and then made the trip back. About 2 hours and roughly 140 miles my tuner was reading high EGTs and began defueling. Temps were in the 1200s. I stopped the truck popped the hood and could hear the truck sucking in air and didn't not return to low idle but remained at 1100 rpms. The exhaust was extremely hot and I would estimate around that high temperature. I called bullydog and they told me jack s#*& but that my tune was out of date and to unistal the program and update it.

I uninstalled the tuner and drove the rest of the trip without any issues.

I have noticed that after unistalling the tuner my Turbo pressure is not as high as it was with the tuner set to no power.

What I'm asking is did the high EGTs mess up the turbos? What else could be the issue for the exhaust all of a sudden have high EGts?

Sorry about the novel but I figure better to have to much info than not enough.

Thanks guys.

You still have the DPF on.

Pretty sure bully dog is a dpf on tuner so my guess would be you went into regen.

Yes that is probably what happened. I have talked to Bully dog and they do not do any DPF deletes. I have purchased H&S mini max tuner as well as an EGR delete and 5" straight pipe. I have been told and researched that this will make a substantial difference in my pickups ability and will aid in the longevity of the motor as well.

The difference will be night and day. You might want to get an intake aswell incase you didn't get one already. You won't regret buying any of it trust me ahah

I have been told that an intake could potentially ruin the motor due to large dirt particles entering the intake. I drive many dirt roads and fear this could be plausible. Any takers on whether there are certain filters that work well in off road applications?

I can't help you with which filter to pick but Most trucks running bigger tunes on the h&s with stock air box will choke the motor from lack of air.

well I will just be running it on the lower setting and only turning it up when I feel the need for laying down some Prius repellent if you know what I mean. HAHA
