I tried to change the tire size on this new style 08 Chev K2500 6.6 LMM but I got this message: "File not supported-Definition failed to load. Please e-mail this file to [email protected] with a VCM Suite Info log." I e-mailed but no responce yet. I have version 2.2.0.0 and have tuned an 07 and 08 new style gasoline with no problems. What am I doing wrong?
