I would have to say..Yes :laughing:


I went and calculated my trip (yes thats the trip miles) and by my GPS it was only off by 25 miles. understandable with re-gearing/reprogramming and 37's. the hard calculations gave me 11.5

So ya, its pretty accurate. :laughing:

Oh and that is the MPG towing a trailer with all my shat, I think my weight total was like 8k (will post up actual later) and 3 states I was fighting a head/cross wind all day :shaking:

No mine is off by about 10 MPG, I think it has something to do with the Blower, i get 14ish but it reads 22-24 MPG.

Mine is off 1-2mph. My speedo is 1mph fast I believe. Never been able to get it 100% dialed in.

Did a 1200 mile trip last week-end. 57 gals (imperial, not U.S. gallon which is 4/5 of Imperial gal). Fuel cost an average of $5.80 per Gallon.
Calculates to 21 miles per gallon.

Computer said 21.5 on average.

My dead stock rubi has always read about 1mpg higher than I actually get.
thats because it wants you to put bigger tires on it to even it out haha


and not sure about mine, it says 17 but i dont really believe it. I will have to fill up and do the math
