I am going to start with sorry, I am sure this has been talked about before. I have the mini max on my 2009 LMM with basic mods. My truck has a huge hesitation and power comes on and off just as quick, Is there anyone who customizes the tunes on these or can direct me on how to improve my performance and fuel mileage as I am still only getting 10 MPG.

10 on a basically stock LMM ouch! Or is this towing perhaps? I have no direct experience with H&S mini but have heard/read that their tunes aren't always the greatest. there are some great tuners out there that have put the time into developing their tunes. BUT i will say you should verify you don't have anything else going on. Any lift or big tires? Stock tires stock tune i average 17 almost 18 (hand calc'd). I have a level and 35's and i'm in the 16 range now.

I run a minimal in a 09 4x4 lmm 3500 long box crew cab, nothing fancy but I can tell you on the tow haul tune I get awesome mpg.
I consciously run smaller tires and be easy on the peda but I do let it sing on the hiway and I do calculate by hand
