Tuning 6.0l for efficiency

[wildbillracin]

thanks for the heads up. I know that this truck is not going to be any economical vehicle of any sort. I am playing with the DFCO lightly. Is there anything I can do with fuel/air, timing or transmission tuning to help out econ?

Right now I am on a 6.0L 4l65e in a denali so similar in some respects.
I have found that the transmission tuning and torque management decrease really makes things come alive and feel so much better. I figure when it requires less throttle input to feel like I am going the same speed I normally see mpg increase. I have yet to check and see if there is a real world increase from the trans tuning yet since I am onto the fuel and timing right now but I feel it had to have helped!

Look at Joecars input on the top of the trans tuning section and it really helps out (he has helped me a ton with mine!)
