Calibration help with H&S and Lie-o-meter

just performed all work on 08 F-250 2 weeks ago. H&S tuner, cat\dpf delete and truck runs awesome. My lie-o-meter is way off saying I am getting 34 avg. mpg and I know this is wrong. How can I recalibrate the Lie-o-meter to the H&S tuner to get an accurate reading?

AW794, how far off is it from your hand calc? pre-mods my L-O-M was only .5mpg off. I suspect it's over 2mpg now, but the thing is getting such good mileage, I haven't had to fill up since mods went in. still 1/2 tank after 3 weeks.

My L-O-M is off too. I just learn not to look at it and use a pencil/notebook to find my mileage.

I don't think there is a good way to calibrate the meter.

Mine is consistently 10mpg off. Filled up today. L-O-M said 23mpg. Hand calculated 12.9mpg.

mine appears to be off by 7mpg-no matter how I drive it. I've checked after 4 fills since removal. Hand calc. in this order- 13 mpg(testing and racing around), 18mpg(all highway), 15mpg(towing about 6000lbs) and 17mpg(city/hwy mix). Each time my gauge was 6 or 7 off.

Mine is typically 9-10mpg off as well.

"don't mock me monkey..." (don't know if you've seen 'Grandma's Boy'. that was a quote from it. so no offense intended.)

if you are serious, I am disappointed too. I was hoping to baby it and get over 20, but I didn't want my bubble burst this soon. my old 7.3 was getting 17-19 empty and I was dreaming of a little better.
