Speedometer Recalibration

[SickStroke6.0]

What's the best option? And the cheapest option? My speedometer ends up being 5 mph off... so when I'm going 60, I'm actually going 65! I'm glad I haven't gotten a ticket yet!

I just use my GPS, you can put a superlift truespeed on it and recalabrate.

Truespeed works or find someone who has a scanner like an autoenginuity and they should be able to correct it as well.

Do you think my local tire store could do it?

If it's not something you will have to do frequently just go in to Ford and have them recalibrate it. Dave had it done since he put on his 35" tires and I think he told me it cost him $60. I wouldn't waste the time or money on a truespeed or similar device. They cost around $200 and for an extra hundred or two you could have the autoenginuity tool that does a hell of a lot more than just read codes or recalibrate speedometers.

I use the superchips tirepaq, NOT running the superchips tune just recalibrated the speedo which was 7 off

when I set the revs per mile with my sct will it fix the speedo?

No. That only affects shift points in the tranny.
