Actually, I believe that it is fully legal for ROAR. I used this method at last years stock nationals and recieved no beef about it. Personally, I don't think that there is a difference between what I am doing and what break-in drops do. My method comes from Big Jim (who is a jerk btw) and a more in-depth/deeper tuning method.
No, I do not have AIM or Yahoo, but just ask here and I'll hook you up.
