Anybody in or near So IL that can recal my speedo for 295's?? I dont know much about the programmers, so I dunno which ones can do it or which ones are vin-locked, etc.... ???????

 

Bullydog downloader will do it and I don't think it's ECM locked. Just the tunes are locked to the truck......but I had my Bullydog go haywire by raising the tire size (according to bd) up to 34". I raised it to 33" then it wouldn't go back down to stock size. I wouldn't mess with it with the bullydog. Just know you're going a little faster than the speedo says and putting on a few less miles on the odo in the process.
