So my goal is MPG and longevity. I figured lower hp would mean better mpg and and longevity of the engine and trans as long as it didn't lug.
Double R is busy and has a lot going on, I will get warp tuning eventually from him, but I thought I would learn more about what I want, while getting used to the truck and the Ultra tuner.
I'm curious - I asked Franz what to put some setting at for mpg and if there was a chart on what to select. I was told the higher hp tunes will give you better gas mileage if you are light on the pedal. I know you ussually give up one thing for another. I assumed power for mpg, but maybe as the tunes go from 0 up they are better and more effecient. So then I got confused a little.
I guess it makes sense that with a better tune you would get better timing for combustion, higher fuel pressure = a better mist, higher air/turbo = more o2 to detonate.
In regards to using a higher hp tune, can the throttle/pedal then be turned down or limited to compensate for the higher hp so that with a more agressive tune you would be forced to go slow? Would it turn the response down or just set a limit to the throttle?
I was thinking once the ultra is installed is boost a good way to know if I am wasting fuel in a particular tune? So the more pedal, would be more boost, thus worse mpg? Should I watch something different? The RPM seems like it wouldn't work to well. For example, to get out of granny/1st gear it feels like the rpms have to get pretty high.
Another thought, I have a 2012 which is the same 6.7, can I decrease the hp to come more inline w hp specs from '10 or '11 for longevity of the rig? Is the def fluid the thing that makes better mpg in the 13± trucks, It increases the amount of fuel, or what?
