All though I have gotten 24+ I don't claim that. When asked what my truck gets I give every day achievable cold hard truth. 18 hwy, 16 towing a light boat and a miserable 12.5 towing 10k lol.

When I first owned the 07 classic I have now it would get an honest 20+mpg with the big tune as long as you didn't get on it. It would get about 12 towing my travel trailer. After I bought it back and it has the 6" lift along with weighing close to 1000 lbs more I get about 17.5 on the highway and 15 around town on the small tune. Still in the 11mpg range towing.

So I was told by a guy with a lmm that he gets 24mpg towing a 24ft enclosed trailer loaded. Has robs basic tunes and a exhaust. Is he full of crap or?

Towing, 24mpg......the guy's full of crap. But Rob's tunes are very good. In Jan. 08 Nathan installed a 475 kit, Rob did EFI with a DSP5. Engine was stock with exhaust. Driving back from Boise on #3 tune the DIC said 22mpg.....hand calculated was 21.7mpg. Another trip of mostly 70mph highway with a few full throttle stomps, switchback mountain driving, all at altitude.......after about 550 miles (53gal. tank) hand calculated was right at 22mpg. Towing wouldn't be anywhere near that, no way.

I use to get 20mpg in my truck all stock cruising 65 on the 37s. Any wind or hills and it dropped. Towing with the twins I could get better, somewhere around 12ish. With the 45% over injectors, it's been a long fight to get mileage back up. Highway best I get is 17 unloaded, with the trailer I average 10, sometimes 11. I can't bitch though, it's better than what I see a lot of other guys get and I'm pushing more hp

Really depends on the altitude and altitude changes, I get 9mpg going to work but I'm going 80mph from 3000 elevation to 6000 in less then 15 miles

Best i have ever gotten with Rob's tunes was 20mpg on stock turbo and trans. That was me literally driving like a grandma. Not sure what kind of fuel mileage i can squeeze now with the setup i have now

Thought you were moving back to Idaho, whatever happened to that first twin set up that Nathan built for me and you ended up with?

When my LMM was new, it set a record pulling a 40ft 14,000 pound boat. I got 120 miles on 21 gallons.

What part of Idaho? I'm in Blackfoot. If I ever get healed and if you ever get that timbersled, we'll need to go play. If all goes well, I'll be back in the saddle by this time next year. I've got alot of tips and tricks with the snowbikes too, so don't be afraid to hit me up if you purchase one!

best i got on my black lbz was a bit over 21mpg on the race engine and big twins. New engine and tow twins are about 19mpg and between 12-14mpg towing my race truck around.

Although i got 62.2 mpg going up to McCall from Boise and back a few weeks ago.....

I will probably go back to Boise. I have friends and family all over Idaho, I grew up in Salmon and the wife is from Rexburg. I need to come visit Blackfoot anyway and stomp someone's azz that sold me track off of Snowest awhile back:D I will hit you up when I get into town.

I plan on building a snow bike for sure. Still messing with sleds for now, 2012 Proclimb 925 with a turbo. Need to get everything put together and some friggin snow would be nice:mad:

Like most everyone says, he is most likely not calculating correctly. Average we hear about is that 19/20mpg empty. I do have a local customer with an LBZ that has been getting 24mpg average for years on the highway but that is a freak truck. I told him I want first dibs on it if he ever sells it.
