SCT tune back to stock?

[Craig]

Forgive my ignorance with these computer controls, but I bought an SXT X2 tuner several years ago when I had a shop do a performance tune. Can you change the tune back to stock using this X2 or does it have to go back to a shop? I made another post about my O2 sensos being turned off and I can't go through emissions now.

If the tune was loaded in your car with your xcal2 then you can return to stock. The tuner is married to the car.

set it back to stock tune drive it for about a week so it runs through the readyness then take it back to get tested if you take it back to soon it will not pass
and you don't need to turn off the rear o2's to get a good performance tune

i went straight to the emission station after new tune loaded. Only about a mile, and it passed with no problem. If your going to flash back to stock,remember it won't work with a aftermarket CAI..
