Hi I got a 05 c&c 3500 dmax and I already replaced the rear tank sending unit and the the transfer pump because the gauge didn't work and they was bad. I cleared the codes and it read correct for a day or two and read empty again. Went to fill the tanks and the front tank was full and the back was about half and it keeps reading empty. Everytime I clear the codes it works for a little then stops again. I was looking and found that theres a tsb out for that problem and one of the things is it needs to be reproggrammed. My question is can I do the reprogramming needed with efi live? I have a v2.

Thanks,
Cliff
