I've got a 2011 and I just installed a h&s with a dpf delete but when I crank it up the info screen in my truck stills says exhaust fluid tank empty and it says speed limited to 55. Is there any way to resolve this issue?

Give us a call. 888-628-1730. There are some factory flash issues out there that contain DEF problems. We are working on updating all the flash files to the newest GM calibrations that have fixed these problems.

How long have you had the tuning on the truck? Was the message present when you tuned it? Did you follow the emissions removal instructions exactly?

You will not be limited to 55mph, or 5mph. We turn off the speed limitations in the ECU so that this will not be a problem.
