Default modifying stock tune

Can I use the SCTX3 that has my bamachips tunes on it to modify my stock tune? If so, how? I want to update the axle ratio since I changed from 3.31 to 3.73.

Thanks!

USER ADJUSTABLE OPTIONS
Adjusting User Adjustable Options
User Adjustable Options are contained within the pre-loaded tuning files. You will be
prompted to Adjust User Parameters—Yes / No. To adjust user options, select Yes.
The Adjust User Options menu will appear and you will navigate through the options
using the arrow up, down, left & right keys. To enter the option or select the option,
use the select key. To cancel the option or go back to the previous screen, press the
cancel key.
The user adjustable options allow you to adjust common vehicle parameters such as;
Fuel Octane, Rev Limiters, Speed Limiters, Axle Ratio and Tire Size Calibrations,
Engine Spark, Engine Timing, Fuel Table and more.
The available user adjustable options for your vehicle will appear in the on-screen list.
Use the arrow up & down keys to scroll through the options list and use the select key
to enter and modify any option.
Once you have selected each option to change, you will be prompted to save all
adjustments. Once the adjustments have been saved to file, you will be prompted to
continue the upload process.
Many common user adjustable options are listed near the back of this user manual. If
you have any questions regarding the number of available options by vehicle or how
to adjust any of the options, please consult our tech department or web site for further
technical assistance.

Thank you for the prompt reply. I know I can adjust the preloaded tunes; I can't figure out whether I can modify the stock tune using the tuner. When I went back to stock the ecu thinks I have the 3.31s and it runs like a v6 performancewise!

Geico.
I believe stock tune is stock tune.
No messin with it.
Get an OEM stock tune from bama with
your axle ratio value only changed...

Hrm...I know I could in my Diablosport Predator so I suspect you should be able to in the SCT. I never looked at my SCT X3 to see since I had my motor built so no more stock tune for me :-).

I went through the menus pretty thoroughly and didn't see a way, but I'm no expert so that's why I asked. Thanks for all the responses!
