Default DTC's

I am new to this forum and am looking for some help. I have a 2007 Megacab with the Hemi and have a Volant COI, a Magnaflow muffler and have installed a Hypertech E-Con Max Energy programmer. I took the truck to the Dealer for an Oil Change and put the program back to stock. After I left I put the program back to run on regular gas and 2 DTC' came up. They were P0000 and u0100. Does anyone know what they mean or why they came up. Thanks

No Communication with the Engine Controller (CAN)

I think the P0000 is a result of the u0100 which is the issue above. Hope they can not tell you were tinkering with the PCM.

Try plugging the programmer back in and returning the stock tune. If that works and no codes, you can try the programmers tune again...
It's possible it didn't copy the whole tune and the programmer is sitting there without ANY valid tune on it saying, WTF???

I called Hypertech and they said that the P0000 was normal. I set it back to stock and then reprogrammed it back to run on regular gas and it was fine except for the P0000 which I am told is normal.
