I just installed the speed cal and the number the guy gave me was 3,5,7 and i called about 20min ago cause i just took it out driving and it just didnt seem right at 70-80mph so i called again and sure enough they tell me ,3,5,7,10 now. Does anyone know what i need to set the top and bottom to? So far dallas mustang isnt being that helpful.

They are 0's and 1's. The 3rd 5th 7th and 10th all need to be set at 1's the rest staying down (i believe).
 
i have 285-40-17 and i told him and both times they told me something different. I told him stock gears were 3.08 along with 225/55/16 and then just told him what i got now. Guess ill try the 3rd,5th,7th and 10 one this time.
 
The one on american muscle is like a data table, nothing you have to type in. Was that what you used? Ill try calling them tomrrow to see what they say0 I just wish i didnt keep coming up with different numbers haha. What rpm's are you at(auto) at 50-55mph and 80mph? Thanks man.

That would require both of us having the same gears, and I really couldn't tell ya. I forget.
 
I wish I could say I had the solution for ya, but just wanted to say I feel your pain. When I bought my car, I found out it had a speed cal in it, and well it was off. Then bought a diablo tuner and well just played with the gear ratios and well got it pretty darn close. But GOOD LUCK!
