Just put on my new ehaust and boost controller, what can I do to get rid of the check engine light..

pull the ECU(?) fuses for 20-30 seconds. I think they are the two most inboard ones (I always have to look). www.mkiv.com has the answer.
You can always disconnect the battery but that usually resets the clock and radio and stuff.
