New to this site. I have a predator on my lly. Is their anyone running it? What kind of fuel milage do you get? or have any problems with it on?

Lots of people run it. I ran it on the 85 tune for a while. Iwas getting 17-19 mpg with my 04 LLY.

yeah i don't evan get close to that. I get around 10 - 12 on the 65 stage no matter if i am towing or empty. the best i got was 16 mph when it was stock

I ran 65 hp on my '05 95% of the time. I got a solid 20mph hiway @ 70-73 mph. 18 mpg daily driving on rural roads @ 60mph avg. Ran the 100 hp tune on some long hiway trips and got 20+ mpg @ 70-73 mph. 43k miles and no problems.

I run mine on 65 and my last tank was 21.8mpg, hand calculated on the highway at 65-70mph.

i've been running on 65hp tune for about 20k and my fuel mileage hasn't really improved... still 16-19mpg depending on the driving conditions. But I still have factory exhaust & intake though. Hopefully i'll see some improvement once the cat is gone! The big difference that the predator made for my LLY was major improvement in acceleration and lots of black smoke for the ricers... ;-]

My mileage is very similar to what the others report above. I run it at 65 in the winter and 85 in the summer.

Every truck is different. Some get great mileage stock and others do not. Some get great mileage tuned, while others do not.

I'm still waiting to break into the 13's with my new 07. (Impatiently waiting I might add.)

I'm running 85 and sometimes 100 and currently get 17 highway (75 mph) and closer to 15 or 16 in town.

gets a little better w/o winter blend fuel.

I get a crazy 13.9 to 14.2. I have 35k and I am waiting to break mine in also. I run the predator on 80whatever or 100whatever it does not matter because I drive like a old person, slow, easy and in front of whatever I want too.

I just ran the 65 hp tune on the way back from MT... 1400 miles and I got about 19 mpg overall running 70-75... Not too bad considering that the temps averaged about 25 degrees... This was unloaded with the winter front on it. I ran the stock tune on the way out to MT and the mileage was just a tad bit more... I did run 60-70 though, cause the weather was not soo good.

I get about 14-15 with the way I drive (more hard driving than not). Love the power.

I am getting 15-17 empty on the 65 tune and about 10.5 pulling 9500lbs+/-

Hand-calc'd ?? If so, that's really good!
