Ok, so I got 4.10s installed by a ford dealership but at the time I was running a bamma tune and told them not to flash my car bec I would just adjust it with the sct. Now I have the stock airbox in along with the stock tune but the sct(xcal2) wont let let me modify anything. I went back to ford and he treid calibrating my spedo but on his laptop he could only tune it for 3.33's,3.55s and 3.73's. He told me that I could get a ford racing device with the stock tune and adjust it that way but I would rather not have to spend that much cash. Does anyone know of a way i could run the stock tune and have my spedo set for 4.10's. Or do you know if a tuner could send me a copy of the stock tune so I could adjust.
Thanks in advance for your input and happy thanksgiving

you could also go to your local tuner, they should be able to make changes in the calibration to run 4.10 gear.

 

First, I don't understand why you have the stock airbox on. Did you return the airbox and tune to stock just becasue you had the dealer install the 4.10's?

When you say the Xcal won't let you modify anything... Is it letting you load the Bama tune? If your Xcal is locked out then it sounds to me as if the dealer did reflash and your strategy code has changed.

 

the xcal lets me modify the bamma tune but not the stock one. I called a tuner and hes making me a stock tune with the 4.10 adjustment. Problem solved thanks

 

Why dont you just get a tune for it... it'll run much better...
