Well, I'm glad you're being cautious with it, I wouldn't want to see you float some valves. Power is falling off pretty hard after 7400 RPM with stock cams. I wouldn't mind seeing the A/F logs for the pulls, if possible.
N1's are def. nice. I can't wait to see what JWT manages to come up with later this year, for the VE. Don't forget to throw a GSpec water pump pulley on your setup (if you don't already have one). You will notice improved throttle from down low all they way up top. Underated mod for sure!
