Tire size - speedometer

i adjusted the programming for my 37's, mileage is back to where it was with the original tires as well as having an accurate speedo. the tighter shifts and performance improvement make it even better .

Alright... stupid question, but what exactly is "one of those hand held programmer thingys"... and is that the way it reads on the box? Because in Latin, "programmer thingys" means, well... something else all together.

Phil,
As usual, many thanks and great help you are! I'm no mechanic, but could certainly find my way out if I crawled up under the hood... is the Superchip easy to operate? And the 'diagnostic connector'... easy to find and hook up too?

Thanks Phil

If you can use a calculator you use a programmer.

Lift / tires are installed tomorrow... afterwhich I'll purchase the Superchip and give 'er a go. Thank you!
