Thanks for the reply. Over the 2 years I have averaged 18.9 mpg( about 20,000 miles ).That is 50/50 city/highway. Not too bad for a 3/4 ton 4wd ccsb. Believe me the truck will haul ass. Great tuner.......wish you guys made cell phones I'd buy one in a second.

Almost 2 years have gone by since I installed the predator tune. She still running good but have been thinking about about upgrading to the intune. Is it worth it or should I stay with the predator?

Dachief I loaded the 120hp tune almost 1,000 miles ago. It's a little smokey when you get on it but seems to increase city/highway mpg a little.

Well the 120hp tune does yield better highway mpg then the other tunes. According to my figures right at .5 over the 85hp tune. Thanks guys for the predator. Works great.

I've been running the 85hp tune on my 06 lbz for several thousand miles. Decided to load the 120hp tune on her today. We'll see if there is any increase in fuel economy on my road trip.

I agree. The 85hp tune nets me about 19mpg city/highway.

I have an 06 LBZ. My mileage in town was about 14mpg. On the highway it was about 18mpg. After I purchased my predator and installed the 65hp tune I added almost 2 mpg to both city and highway mpg. Since then I have been running the 85hp tune. The weather has warmed up so I'm not able to make a ...

My friend had trouble loading a tune the first time until he removed radio, radio amp and info fuses. His was an 07 not an 08. Worth a try, may prevent voltage interference.

Did you pull the 3 fuses from under the hood and keep your doors shut?

I put the 85hp tune on her. wow, I hope I can stay off the skinny pedal.

ok I'll try 85hp tune next.

Just an update, the 65hp tune is great. My mileage has increased by almost 2 mpg highway/city. Tansmission shifts have improved from sloppy to firm, wow what an improvement all the way around. I'll post some mpg numbers next week....

I've put about 300 miles on my 06 lbz since putting the predator 65hp tune on. I'm impressed....should have done this sooner. Thanks for the hard work diablosport

Everything went smooth. Adjusted tire size and put the 65hp tune on. Took her for a 25 mile drive....diffentally could feel the difference. Can't wait to see what mpg I'll get. DIC went up from 18.3 to 20.5.
