I'm lucky to get 15 unloaded hand calculated. I get the feeling one of them believes the dash
i have had a few customers reporting over 20 mpg in a ******d 6.4 towing. a 6.7 wont touch that. whats the difference between the two? is it tuning or just that a 6.4 gets better gas mileage.
Yea I know. I just wanted to see if it was real. Becauz my truck would be for sale lol. Jk. But yea it's hard to sell a customer a couple grand in parts that won't get them better mpg on their new rig when they were "getting" over 20 hauling in a 6.4.
