It still must be breaking in? Does you regeneration light come on, and then a few moments the smell?

have your dealer check for leaks... seen a few that can be hard to find...
direction the wind is blowing is also something to factor in...

Thanks for the help....it is only while in town. I have had it to the dealer 3X for this but can't find any leaks. I love this truck but I still love my other truck for MX racing!!!! Ford E350 box van 7.3 4" stainless exhaust, banks chip 250,000 miles no polution junk and running strong.

In some cases thats commin when the dpf's are in regen mode.I've had that issue on some of the big rigs when they are in a regen.And as for the regen cycle causing a small power loss, and a mpg drop,that's also commen with the dpf's.The big rigs are the same way.

Mine too.
It only smells during the DPF's regeneration around town in the stop and go traffic. I can't smell it on the highway

Is the truck bone stock?

I've been all over these trucks. And familiar with the burn off process.

To raise the temp for burn off the engine injects fuel into the exhaust stroke. It would be impossible to get an oder from there. Look way back on the fuel rail near the fire wall and see if you can see wet places. You might want to feel back there with your fingers.

The other place to look is at the CP3 (Injector Pump) Check all the fittings.

Also pull the dip stick and smell the oil

Those are typical places to look and a good add to the information. but this is usually but not always the Emission systems doing this.

When it comes to the fuel rail system,(NEVER) put your hands over the fuel rail and lines to see if there is a leak. The fuel rail system pumps very high fuel perssure,In some systems in an excess of 10/15,000 psi.If you do have a fuel leak there the fuel can penatrate your hand and inject fuel into you which could really hurt you. Check visualy, Or have a shop run a fuel pressure check with the right eqipment.Better safe than sorry.
Also please fill out your signature so we know what kind of vehicle you have and what motor.
