Your restriction is going to be in the intake as it will only flow about 750 cfm. This kit is not going to get you past 605-610 HP without some others changes. I have been working on a combination with Bob Madara that we dynoed for the first time yesterday and made 608 HP and 618 TQ on the first pull. As you can see on the dyno sheet we are running lean and have some fuel re-maping to do on Monday. Our goal is a 630-640 real #'s HP package.
