Fuel Economy 3mpg lost in latest

[Excursionist]

I have a 7.3 l and was getting 21-22 mpg highway and 17-18 city. Now lucky to get 18 highway and 15 in town. Whats the deal? I have noticed the fuel has been decreased to 80%. Is this the reason? Or was this just done for stacking purposes.

Where did you see fuel decreased?

I have been getting rave reviews here from guys who updated to 9r04, this is new....

[Excursionist]

how new is the 9r04 thought that was just an update for a cal id missed in the 03.
I noticed the fuel in level used to always say 100% and now they fluctuate.
So why the huge mileage difference?

I have no clue, there were no changes to the tunes as far as I knew.

I am asking for an analysis of the newly written 9r03 100 hp tune file and find out the differences from the previous tune before I had my tuner sent in to you and upgraded. The new tunes are costing me $20-$30 every tankful. Where is SohFast he can fix this i am sure

Brian is no longer with us, but is still lurking looking at these tunes...

Mike, the difference in the "feel" of the tune is the power or fuel is not as linear as before. the new 100 hp tune seems to be just all out fuel dump
