You will want to have your battery unplugged while doing this mod. After you're done turn the ignition key to on and let it set for about 15 seconds, then turn it off, pull the key out, put it back in, turn the ignition key to on wait for another 15 seconds and start her up. The ECU will be set to the TB and start tuning for the increased air flow.
