When it comes to flashing vehicles, sometimes its all just too easy to plug in your flash tool or remove the ecu and just pull the calibration data with little or no thought to checking over the vehicle before starting. This is where many fail before they even start.

You should have some sort of procedure or method in which you follow prior to carrying out any modifications.

Please follow these steps Basic OBD Tuning Procedure
