so i did some testing the last few weeks to see the difference in mpg with my juice. I have had it over a year and really havent noticed much change in mpg with different settings and driving styles. It started with a trip, mostly interstate with juice on level 5, driving 80-85, i got around 15.8 mpg. the next tank which was normal driving, 75% highway 25% city, i got 15.3 mpg with juice on level 5. Sooo the next tank i ran on level one which is supposed to be economy mode and i drove lightly in town and 70 mph on the highway. I got 16.3 mpg with that setting which was not too impressive. So i guess my conclusion is id rather drive on level 5 blowing smoke everywhere and have fun than driving like a grandma and saving a few measily bucks

 

Has anyone else seen an IMPROVEMENT in MPG with the JUICE on setting 1, with the fuel set to 1?

 

my juice did nothing for my 06 for mileage, my bdtd does though and way easier to install. lol

 

I saw a 1 mpg (hand calc.) increase after putting on the juice/attitude, but I usually leave it on 3. I left it on 1 for a month or two and saw no increase in mileage. It runs nice on 3 and I get better mileage, I like it.

 

Mine on level 1 and 2 got me 17.8 and 17.9 on a 1700 mile trip this summer. Ran 75 and 80 for 90% of the trip. Of course I have the 305 motor.
