Brought my truck in for the AC seat TSB fix this morning, and also asked dealership how much to recalibrate speedometer to larger tires. They wanted $125, so I told them to forget about it...seems absurd, no?


Also, I'm planning to get a tuner at some point anyways...can't I recalibrate the speedometer myself once I get the tuner?

 

Depends on the tuner but yes most should do it.

I can tell you for sure that SCT can do it, and when you order your tune file your tuner should be able to write that right into the program.

 

For $75 more there is a use Gryphon for sale on here today and you can fix it with that and have tunes...
