I have been told by a few people that they are getting 21 mpg's out of their 6.2 litre 1500's. I was thinking about going with the 2500 with the 6.2 and having an EFI Live tune done on it. Does anyone know the specs (HP, Torque, MPG's) on a 2500 with the 6.2 and 3.73 gears?

Yep, 1500 only. I also haven't ever heard of anything near a 21mpg average from a 6.2 truck.

I have a 2010 Silverado 4x4 with a 6.2 and I am only averaging about 13.5 mpg. I have read other post on this site that claim there 6.2's are getting 16-18 mpg, but I know my truck is not.:down:
