no need for a reflash yet. Your ecu will go bonkers after the cai upgrade. ECU will adjust by itself after about 300miles. Mine hit down to 12 mpg, but it was incorrect reading. You can reset it by disconnecting the battery if you like. 24 hours to be sure.

Just use the pedal method, its a lot faster and easier. You also have to rub your stomach and pat your head while doing this
