Hey guys, I'm new at this so go easy on me please.

I have a 2010 f350 and was within minutes of ordering the Spartan programmer
and decided to check the FAQ.

there I found that I could not calibrate my speedometer for larger tires.

is there a programmer that will give me as much flexibility as the Spartan and allow
me to recalibrate my speedometer?

Thanks in advance, I've gotten a lot of useful information from reading these forums, keep up the good work, I still have a lot to learn.

In short no on the the new trucks its my understanding that the speedo is precalibrated with only options for stock tire sizes. The options on the tuners just allows you to tell the tuner what tire size you have and it display your actual mph.
