Question Tuner to adjust speedo and shifting

What do you guys recommend as a tuner that can fix tire size and shifting points from the OEM tire vs new different sized tires? (Or perhaps make them even better) and fix the speedo?. I have a 2013 6.7 SCREW Lariet 4x4 SW and with almost a 7% speedo error.

I know squat about tuners so advice would be appreciated.

Ed

I went from the stock 275/70R18(33.2" tall) to a 325/65R18(34.6" tall) and according to my GPS my speedo is out by 1km/h at 110 and almost bang on at 100km/h... so what size did you go to get get 7% difference?? Did you GPS that? As for the tuner it all depends on if you want warranty or not. If you don't care about warranty then get an H&S Mini Maxx but if you don't want to lose your warranty then go to a Ford dealership and have them adjust it. Or you can get a Hypertec inline module that will let you entre any tire size and gear ratio where as most tuners and the dealership can only go up to a 34.1 in tall (factory) size.

H&S can go up to a max of 34.5 tire which is the biggest factory tire available. It would be pretty close if you're on 37's still (assumption if you've got a 7% speedo error) it also is capable of adjusting the shift points/shift firmness and various power levels for performance. I've been running the H&S for the last year and 20k miles deleted and it's amazing what these trucks can do.

If you need more calibration for the speedo then that there are several companies making a standalone calibrator for tire size but I can't remember the brands offhand.

I got a set of winter tires and rims from a 2012 F-350 XLT with the 265/70-R17 rims. My OEM rims are 285/70R-18. Just did a re-check of the calculations - it's 4.7% too fast now.

My dealership did not adjust my tire size because they didn't know how. If I'm to go back, what do I tell them? How do I get them to adjust the calculation for the tire size when they didn't offer it as a solution? I'm guessing some incompetence is happening on their side, but I want to help them fix this. I was thinking a tuner could fix it simpler, but if its' something the stealership, I mean dealership can do, why not?

Yes the dealership can fix it. Call them, or go back there, and tell them that your speedo is out and you want it adjusted. Even if it cost a few bucks, its still cheaper than a tuner and you don't void you warranty.

I've given them a call to see why they didn't set this yesterday. Kind of frustrating.
