    I would swear one of the tuners had a 'eco' tune that would turn the AFM on more often?

    Nice welds

    I have a 2" level and would go with 275/65-20 if I were to do it again. Lots of room with the 60's

    Not sure what to tell ya. Go faster? I was knocking down just as good of mileage at 73 or 77 than I do at 68 or 70. I have a tonneau cover as well. Getting about the same mileage on the highway as my 5.3. Actually I am getting a better all-around average in the 6.2, perhaps the 8 speed has something to do with it. I saw 13.9mpg a lot in town with my old truck. Both trucks were 3.42 and both on oversized BFG KO2's, with the speedometer corrected for tire height. My 2014 Silverado double cab z71 4x4 with the same level and tires and tonneau

    Reminds me of my dad. Refuses to even put 5W-20 in his F150 when the oil cap says so. "I like the protection of 10W30", and then runs 20W50 in the summer.

    This is the second tune DiabloSport provided me. The tuner didn't recognize my truck (brand new 2015) out of the box, so I sent them the unknown_pcm file and they sent me a tune that worked, but I couldn't adjust anything like AFM or tire size etc. Then they sent me a second tune and everything acts like it should.

    I have 10-ply BFG's and don't think it rides rough at all

    Bonus: If you didn't correct your speedometer, you're actually getting like 19.65 mpg if you see an indicated 19.0 mpg with 33" tires vs the stock 31.9" tires.

    RC 2.5" on my 2015 Sierra SLT, had to drive it down a curb to see if the steps would scrape (they didn't)

    Guys are doing it, you have to move the sensors http://www.gm-trucks.com/forums/topic/168618-leveling-kit-for-2015-sierra-denali-magnetic-ride/page-3

    Same here. Mike just gave me a new tune that I will install shortly
  15. robvas
    AFM is still enabled on my truck (damn diablotune has been a pita) and I don't get the helicopter sound with a magnaflow like I did with flowmaster

    Guy at work has them on his dodge. I think they look pretty weak IMO The BFG AT KO2 looks way tougher. Have you considered 275/65's? That's what I would do if I were going to do it all over instead of 275/60
  17. robvas
    Mine does the same thing. Posted over on their forum but haven't gotten a response yet http://diablosport.com/forum/viewtopic.php?f=44&t=51146

    That's what we did

    2015 GMC Sierra SLT CC max tow RC 2.5" leveling kit, I did not install the upper strut spacers because I wanted the front to still be slightly lower than the rear BFG 275/60-20's. Wish I had gone with 275/65's!!

    They aren't tightened - I wanted to take a picture to share on the site. If the bolts were tightened the bolt would have went right into the axle/cv shaft.
  21. robvas
    Same thing happened on mine. Had the same guy install my Skyjacker blocks and he didn't have the problem, not sure if the bolts were different or what.
  22. robvas
    Highway mileage, 70-74mph, AC on, 33" BFG KO2, speedo uncorrected
  23. robvas
    I don't see why I shouldn't be able to. I need to contact diablosport again, at first I couldn't program my truck at all and they had to give me an update. I haven't even hit 1,000 miles so I'm not too worried about tuning it before it's even broken in.
  24. robvas
    I know. Felt and looked like a whole new truck when I leveled my 2014. Heck, it finally felt LIKE a truck. Can't wait.
  25. robvas
    Ordered the RC 2.5" leveling kit, hopefully I can get my truck over to Tuffy on Saturday morning and get it installed
