You really are pushing on with this.
Have you had the new cams running yet with the standard intake system.
From what I know of running cams in nicely, they like to be run with a light throttle at about 2000 - 2500 rpm for a few minutes to bed them in to the cam followers.
They don't like tick-over or lumpy running for the first 20 or 30 minutes.
When I changed my ECU, I found it very difficult to get things running smoothly during the first few runs which is exactly when your new cams will need an easy life to bed in properly.
You are probably going to get a decent base map for the ECU but so did I and it still gave me some lumpy runs to start with so It just occurred to me that you might consider giving the cams a bit of running in before you install the new throttle bodies and ECU.
Just a thought.
