RE: Purchasing tuners
It is half true...
As an example... I have the Preditor. When I used it to "tune" my car it downloads my factory tune into the unit.
BEFORE I can sell or give it to someone else to use on their Mustang, I MUST install the factory tune from it back onto my car. THEN, I can use it on another Mustang.
However, I can run all the diag tools on anyones car anytime I want - it will also read and clear codes from other people cars.
