Going from 2 bar to 3 bar tune

[Ryan02Stang]

I currently have a 2 bar MAP sensor Unleashed tune, but received a 3 bar MAP sensor in the mail today, and have a tune from Torrie for the 3 bar.

My question is, do I have to flash back to stock, and then flash the 3 bar tune, or can I just flash the 3 bar tune from where I'm at now?

Thanks!

No need to return to stock first.  Install the 3 bar but do NOT start the car with the 2 bar tune.  Flash the 3 bar tune and enjoy!

Great!  Appreciate the input.

You can flash the new tune without returning to stock the. Install the 3 bar map or install the new sensor then flash.....its just a tune

Changed the sensor and flashed the new 3 bar tune. 

Took it for a drive and everything seems perfect!
