PCV rev extend lets it go to 6200 & if you have cams you should be pulling hard all the way against that, mine does. I really would like to get the extra rev bump because I think I can use it. Either way, if KevinX has given you a map, you'd Prolly best leave it be. In a nutshell, if Kevin, Rylan, Kyle or Lloyd hook you up, leave it till you can hit a dyno.
