Break-in Tune
 

Is it true that you can set up a tune for a fresh rebuild then 2500-3000 miles later it can be automatically change to a different tune with a Tec 2?
got a car with Tec2 and was told by the installer and tuner that it has a rich tune on it for the break-in of 2500-3000 then after that it will be fine... what does that mean?
