[QUOTE="B585Ford, post: 878506, member: 5497"] :whs: I didn't have a EGT issue but I did have a EBP issue with my setup (I would hit 70 (actual EBP) and still climbing when I would let off (and that was on a stock valvetrain). With the help of Dustin, I tried manipulating the EBP tables, then the vane tables and it didn't help much cause when the RPMs get high enough (and the airflow is great enough) compounds can't overcome the restictions in the system (HP turbo, poor low of heads, etc.). The only way I got that down was to cut the PW. Again, with a lot of trial and error, you might get to a point where your power loss from cutting the PW would be minimal. For the quickest spool up, 1:1 is not optimal. On these trucks with relatively stock fuel and turbos, I would say 1.5 to 2:1. Once you light the atmo turbo, then 1 to 1.2:1 would be a great ratio.
