Sooo I got started on my exhaust, CAI, and tuner. Well I had to stop early. Father inlaw said "awe it will be fone you can finish it tomorrow". Well I fired the truck up and got white smoke. Shut it down and tried to load the 310LL. Said it couldnt find a vehicle. Disconnected OBD2 port, waited and reconnected the port. Find the truck and loaded the 310LL. Still wont start. Returning the truck to stock and reloading the 310LL. Jeff told me this tuner does not require bungs on the 5 inch flopro. Other threads on other forums say it does require it. Is this correct? Also said do not run the truck with out full exhaust.
