yes its related to EGT, adding more power requires more fuel, which generates mor heat
Also it seems many people report better mileage with the higher hp tunes. would it then stand to reason the 80hp tune would get better mileage than the 65hp?
not sure
Last along that same line of thinking could the 100hp performance tune get better mileage than the 80hp daily driver if driven moderately?
my understanding is bill writes DD tunes for better mileage than PERF tunes on diesels
I wasn't sure where to put this so feel free to move it if there is a more appropriate forum. Thanks for your input!
