just trying to change the timing is not going to do what you want, because the ECM WILL try to compensate for it after you reconnect the Spout connector...if all your looking to do is get a ittle more power out of it, then your best bet is one of the many aftermarket programmers that are available..if you leave the stock system, then keep it to the stock specs, or it wont run correctly (loss of power, loss of economy, etc.)
