Re: Fuel milage survey

05 1500HD 4x4, 3.73's, I was getting about 12.5 on average. Put in a K&N and did some data logging with Blackbear performance last year. I now average 15.5 or better driving about 75. Anything over that and it starts to drop considerably. On relatively flat ground and 70 mph, I'll get over 16. Plus the performance increase was decent.
