I took mine off to see if it was causing my EGT's to soar. I do not know for sure cause I was boosting at 15 psi then and my EGT's would go over 1600 if I did not let off. Now I am at 12 psi and they are perfect. Right at 1500 on a long pull. I am going to take a little more gas out of it to see if I can get a little more power. Search around and find the post about the VC1 causing EGT issues, you might want to consider not putting it on.
