Vibration under acceleration

[Lonestar10]

it means the ECM has aftermarket trash in it and it could have corrupted the computer cause it not to accept a new tune.

is this true? no but that will be their excuse if the ecm corrupts while their putting in a new file so that they have no liability.

is the computer likely to be corrupted by the flash? no but it can happen.

basically cat is just trying to skirt any liability if something goes wrong with the ECM even if they actualy cause any problem that happens.
