X15 questions

I think you’ve got the wrong idea about me. I do keep my speed down, I keeps my boost down never exceeding 20, I run my truck at the 1400-1600rpm range and cruise at 1500. My torque gauge never exceeds around 70% on the steepest of grades. You’re preaching to the choir. I drive for fuel economy, there’s not much more I can do to improve now other than change equipment. I do not demand or use 565/2050, that is just the program my engine happens to have. I drove it with these same techniques when I had the 505/1850 program.

I’n not saying I’ve mastered the driving habits but I have been applying these techniques for years. I just want to know if the efficiency series would actually be more efficient or if it’s just marketing.
