i already have a good tune on my motor now but i am also putting togeather another motor for about 15pounds of boost this winter so i am running 10psi on a stock ls with a 11psi engine cut using crome. i have the crome pro and my question is can i swap out the stock map for an omni 3 bar and go into crome and select the omni 3-bar and update my ostrich without getting a re-tune?

basically change my tune in crome to tell it i am using a 3-bar and will it work without retuning the car?

You'll need to adjust at least a little bit, especially with Crome.

 

I wouldn't recommend trying to re-scale the map without re-tuning....

 

ok thanks then i will just stay were i am at til i get my other motor ready to tune... and then install the 3bar sensor
