ok thanks guys.

yeah i would use GPS but i got the stupid one that came with the truck and hate it.

i wasnt wanting to get one with a gps because i was going to put an aftermarket one in but the only white one they had, which had the features i wanted had GPS

ill figure it out, im sure 2711mm will be close enough. im never really worried about a speeding ticket here

I often use the previously described 60/60 method (60 MPH for 60 seconds) to see just how close I am with tire size. It work really well for those who don't have a GPS. For more accuracy, set the cruise at 60 and do 5 miles vs. 300 seconds. This will get you REALLY close.

And as Jack said, the speedo is nearly always 2 MPH faster than the actual vehicle speed so even if you're 1-2 MPH off, you should still be safe.

Take care.

thanks Bill

whats the break in period btw, if any??

i can tell the difference in power immiediatly, but one of the main reasons i got it was to try and get better mpg.

especially in Seattle there are alot of hills and stop and go's.

i was averaging 12.5 or so without the gryphon, what do you expect with it?

btw im pretty light on the throttle never really any jack rabbit starts

oh and another thing, i dont have a load previous settings option after i click on "custom options"

however when i went to tire size, it went to a screen saying something about that it couldnt be done or something, ill try it again tomorrow and write it down if it happens again

but then it froze.

ill give it another shot tomorrow

The "Load Previous Settings" is at the *Bottom* of the list. I know, it's a dumb place but that's the way they had to handle the menuing to make it dynamic. Go figure.

I am not certain as to why the Custom Option for the tire size didn't work, or even worse why it froze up. Give me a call when you have time and we can walk through everything and see what exactly is going on.

Keep in mind that you do NOT want to do Custom Options until you have completed a full programming session. It is a bug in the firmware that allows you to actually select Custom Options without first reading a valid stock file from the PCM. If you had already done a programming session, then this doesn't apply to you, but if you didn't then it might be responsible for why the unit froze.

As for break in period... do you mean the engine? In most cases, you should let the engine break in for about 3000-5000 miles, or basically the first oil change.

Hope this helps.
