I recently got an XZillaRaider I Standard, and am wondering which of the three base tunes should theoretically be best for mileage if all driven with a light foot (yeah right) due to more timing and pressure perhaps?

 

there is a tune there for just mileage

 

This is not the new Xzilla

 

I found the best on the 65 level when I had the X1 that was my case anyway

 

I used to have the old xzillerator and ran on the 60hp mode all of the time, but I just upgraded to the new box. It may just be in my head, but I want to say the new box is even smoother and the 65/100 hp settings are even stronger.

Now I don't run on those setting much because you can see what is going on with the rail pressure and it's MUCH higher than when the box is off, but it is fun to turn it up every once and a while.

I also upgraded to the X2. When I had the X1, it was 60hp setting for anything under 60mph. After that 100hp. I was able to get 23 hand calculated mpg a couple of time all hwy. otherwise 20-22mpg was normal at 100hp setting. I'm still trying out the X2 with the MMM program to see if it's any better than at the new 65hp setting.

 

Thanks for the replies guys. I have been messing with the dial but with it screwing up the overhead there is no real way to compare mileage among the settings. One thing I wonder is why even bother with that 30hp tune, I can't even tell any gain from stock, so I was maybe wondering if it was more the economy tune.

The 60hp is a decent bump in power, and the 100 I can break my 35's loose on dry pavement from a stop.
