I just ran 200mi in Nick's light tow, 75mph the whole way got an average of 10.6mpg. But I really should mention the 25mph head wind and the 7000lb sail I was pulling...

So far, I've had real good luck on the(Approx) 110Hp tune I made, it gets about the same MPG as my old PPE 90 tune or up to 1Mpg better so far depending on driving...I really love this EFILive so far !!:rockin

....not to mention all the benefits PPE NEVER had, Like trans tuning and the AWESOME Turbo brake feature!!:D:D






:cool:

I just did a trip to/from Jax and ran the mileage tune on the hwy. I averaged 18.5 both directions.

On edit, this is calculator figuring, not the dashboard comp guessing.

Just thought I would post this up. Filled up in Wichita, KS and headed north. Topped the tank off in Norfolk, NE. just now and recorded a best ever for my truck. Yes, it is relative because of the strong south wind pushing me. I hand calculated: 337.0 miles and topped it off with 12.857 gallons. You do the math. Averaged 71 mph.

Mpg is mpg and that is with a hot tune!!

How many miles did you push it? I've never seen over 21 with my LBZ. I seen 24 with my LB7.

337 is what I drove so far but have total of 550 or so to go ... Like I said though, I have a tail wind. But I will take it with these fuel prices. I could have made the trip on a tank but fuel is cheaper in Nebraska than Minnesota.

That's what I'm averaging. I used to only get about 330 miles out of a tank and now I've hit the 400 mile range a couple of times. That's with my 90hp economy tune.
