Hello All........ I recently purchased a 2015 GMC Sierra LD Standard Cab S/B 4.3L V6 2wd with less than 14k miles on it. The previous owner had it lowered 2/4 using a Rough Country suspension kit. Plus had new 20" Denali take-off wheels/tires installed. This had the speedo off by 5 mph (70mph on dash showed 75mph on GPS). Last weekend I corrected that using RC's Speedometer Calibration module.
I have been a devoted GM vehicle owner since 1988 when I purchased my first new GMC truck. I have switched back and forth between Chevy and GMC through the years but have always stayed with GM. I also own a 2010 Chevrolet Colorado C/C 4x4 with the V8 5.3L (LH9) option and am also a member of the 355Nation forum for Colorado/Canyon owners.
Anyways, I look forward to sharing/searching/discussing any issues I have with the Sierra. I will get some photos posted in the future also.
Thanks all......
