Hey everybody, I am new to this fourm and I herd that there is a way to "re-tune" the duramax to get the factory de tuned power back. just a question, but I heard that you can make some adjustments on the turbo to get more boost but you have to drill the factory plugs out of some adjustment screws. soposivly there is one on the intake as well. just wanted to know if this was true or a line of sh*t???? http://www.dieselplace.com/forum/smileys/Hug.gifhttp://www.dieselplace.com/forum/smileys/Wacko.gif
