How accurate is the trucks speedometer compared against a GPS?
@Rick- his signature has the same tires I am running.

Rick made some specific changes to my tunes to get my speedo dead on...He had to do it a couple times before we got it dead on.... now 70.5 mph on the speedo is 70.5 mph on the GPS...
Before the speedo recalibrate with the LMS tuner, my speedo at 70 mph was 71.5 ish on the GPS.(with the 305/55/20 tires)... Not a huge error obviously but... I still wanted it accurate, especially since it read slow.

Thanks for the quick reply. Rick and I were going to do the same thing but I travel a lot so it was going to be slow.
Good news is we are running the same size tires so that speed setting for you should work for me also

Rick already emailed me my new tunes. 
Now I just need to get my truck back from the dealer with its replaced front pump (was built in the 2 months of bad pumps... Yeah TSB).

Just successfully installed my new updated tunes after a little hiccup on the download portion. I had to use someone else's pc cause i didn't have a program on my mac to install it. Even on 91 oct the new V2 performance tune rocks! 1st gear pulls much quicker and harder now, where as before it took a second to spool up. A++
