    2018 Speedo recal

    Hey guys getting ready to get my wheels and tires from @Custom Offsets. Question i have are what are my options to recal the speedo besides hypertech and Rough Country auto cal. I've talked to both companies and they both say niether supports the 2018 yet.

    Also besides the speedo being off What are the downfalls if any. Will it effect the way the trans shifts?

    I recalibrated my 2017 with my MM3 from @Double R Diesel now that they have cracked the 2018 I would think that should be available for you too, maybe Ray can confirm.

    Yes sir I was going to check with Ray. I guess i was hoping not to have to tune my truck right away or for an option in the 200 to $300 dollar range instead of $1000 + for right now. I guess my bigest concern at this point is will there be any harm in driving it uncorrected untill I can save some for an MM3?

    Without trans tuning, you could experience lugging depending on your driving.
    After I went from stock to 35s, I did in 5th & 6th gears. That's when I called upon the services of Ray @Double R Diesel. The shift points he set me up with made a world of difference.
    Good luck

    I went with 37's I have 3.42 gearing and feel like I am getting a little lugging sluggish at 70 I am only at 13-1400 rpm. Contemplating regearing or trying tunning first.
