hypertech still the only choice?
I want to run 37's but I would like for all my speedo calibrations to be accurate. I've read were forscan can modify it somewhat but not up to a 37. Has any other manufacturer come out with a different option besides pulling the dash apart to install the hypertech. Also anyone have any experience with the hypertech and if so could you share your results. Thanks

I used an SCT X4 device from 5 Star Tuning that would adjust the tire revs per mile to a certain extent to make the speedo more accurate on 2014 and 2016 F250 gassers that I owned.
Other than that I didn't see a whole lot of improvement with the particular tunes I used. But that's another thread and another argument for some guys.

As of last Friday, I don't think so. I have the Hypertech installed on my truck and it works like a champ! I, too, have 37's on my truck and searched relentlessly for something to program the new tire size. The only thing I do not like about the Hypertech is that when I change out my front/rear diff, I will have to reprogram the module from my laptop. Which means...taking the dash apart to get to it (although it was rather simple). I wish there was something out there I could use through the OBDII connection. Unfortunately, FORSCAN won't do it to tires that size.

I would like to have my speedo corrected as well. I'm a little paranoid about the Hypertech though until there are some more positive reports. About six months ago, someone had it installed and it was causing enough computer havoc that he had to take it to the dealer, eventually having to disconnect the Hypertech unit.

This isn't entirely true. I have used FORSCAN to correct my speedometer after installing 37's. BUT, and it's a big but, it has caused a DTC to trigger as the tire size is outside of the manufacturer's specs. Another member, Livnitup is working with FORSCAN to get this corrected, as it is possible on other vehicles. For now, I will just drive with the DTC light, I'd rather have that than the speedo off by ~5-6 mph at highway speeds.
Thanks,
