Ok i installed my mp-8 a couple weeks ago and on the over head sometimes it shows up to 22mpg, but i hand calculated it the other day and it was actually getting a little worse. Can anyone help me out?

My overhead has never been right on, sometimes its way off, but never to the good side, even before I installed the XZT tow box. I just use the overhead to see how warm it is out, thats all its good for.

What are you actually getting?

Your other mods may have maxed up out, it's only going to go up so far...you're still pushing a 4 ton brick down the road ;)

i'm running the same set up you are and milage is a lot better. If you can tell you have the mp-8 on the truck your milage will be bad. Try drivin like your 65 and half blind that what i do.

Cruise control on at 65 i am seeing 23.9mpg on ovhd, did 600mi and got 21.6 hand calculated. Not bad, cause I had a 600lb quad in the bed, towing 2 dirtbikes on a bike trailer, and 3 people in the truck.

Im running the juice on level 3 and the mp-8 on about 75%. I tried the juice on level 1 and mp-8 on about 25% and it went down a little. Driving 270mi at 70mph before the mp-8 i was getting 16 and the overhead was showing 16.3. With the mp-8 the overhead showed as high as 24, averaged out at 20. But im afraid to hand calculate it because i was usually seeing a little less then a half a tank when i got home, and now im seeing barely over a 1/4, so i know its a lot worse then before.

I dont get how those are not better numbers. You said you got 16 before and 20 now with the MP-8? Am i reading it wrong? I get the best mileage with the edge on 5 and the MP-8 on 90%

Thats what the overhead shows i havent hand calculated it since i put the mp-8 on but judging by how much my fuel gauge shows i dont want to. Before the mp-8 i was getting 16...after the mp-8 (overhead is showing) 20mpg. But thats just the overhead what makes me think im not getting as good is the fuel guage, before 1/2 a tank after mp-8 1/4 same trip same miles
