sct and speedometer

does changing the revs per mile on my sct correct my speedo reading? just went from 265/65/17's to 275/65/20's and really like it.

The revs per mile only change the shifting. I wouldn't think Ford calibrating the speedo would change your strategy

It depends reguarding the strategy... If you have the most recent flash theb you should be fine. Ford cannot calibrate the speedo for anything larger than 34" tires if you have a 3.73 rear diff. I just went thru that. The options are either a mod box like the truespeed or auto enginiuity which is a code scanner that is capible of programming the abs sensor. Not sure what your new tires are size wise but my 315's on 16 inch rims are 35" and my spedo is set as close as they can at 65 on the spedo I'm going 70

If you go truspeed it will only serve one function. If you get the auto enginuity it can work as a comprehensive code scanner and scantool for the 6.0 as well as other vehicles. It would really come down to how much each will cost and how you would use it to make the total cost effective. The auto enginuity would have to have the ford liscensing which is at an extra cost. It would probably be cheaper for the tru speed but the ae would do a lot more if you plan to ever work or diagnose problems on your truck.
