So today i finally got my new Edge programmer. I love it! The difference in the shifts is amazing. Got it for a great price too, 150 and its never been used. Anyways, I need to recalibrate my speedometer. I am wondering what the tire size number means. Ive never heard of it. the current one is like 2000 something..

 

It's in the manual, but it's basically the circumference of your tires in mm.

 

Oh ok ok i remember reading that somewhere. Thanks!!

 

hey man if you plan on getting more mods done to your truck. Go to powerhungryperformance.com. They can change your edge into a gryphon and upload custom tunes

 

Ok thanks guys. maybe ill do that in the future. By the way, my gas milage instantly increased by 3 mpg with the edge!!

 

i have an Edge too and i love it, does the gryphon really make that much more of a difference over the regular edge. i have an intake and exhaust

 

Yes it does wonders for the 04-08 so i bet it do wonders for yours too. Just go thier and join up the have a forum section I dont own a 97 up model but i bet bill can make it better for ya

 

Thats a good bonus man

 

I had the Gryphon with canned tunes, I got the custom tunes and it made a big difference. (performance wise. about 1 second faster) I will say, my gas mileage is **** though... I'm getting 13.5mpg or something like that now. 280-290 miles to a tank. I use to get 320-340... Before my Gryphon.

But I also have straight pipes now and mud tires, BUT stock tire size.. and I gun every light and run over 2k rpms.. lol.

 

It's MM bro. In your manual it should show tire sizes and what the MM should be.

3mph increase is pretty sweet. I wish I got that. Haha. Seems like mine keeps dropping, but I gained performance.
