I hope that the battery was disconnected before you put in the re-flashed ECM, if not you may have damaged it. Here's something you can try: disconnect the negative battery terminal, turn on the headlights and wait 30 seconds or longer, turn off headlights, reconnect negative terminal, start engine and drive it as you normally do for at least 30 minutes, this will allow the ECM to learn the parameters of your vehicle. Now see what happens with your mileage.

Yes, the new/replacement computer must be flashed using your VIN. There's no such thing as a "preflashed" unit! HTH. -Jim
