Basically you said having a logged boost source is irrelevant is what I recieved from your reply, which to me is absolutely wrong.
We could argue about this all day, but we won't. You do it your way, I'll do it mine.
I wasn't dissing your sig or saying anything about it other than the fact that knowing what psi you are running tells me nothing unless I know the turbo that is pushing that air, whether you have cams, a smim or anything else that would greatly affect the amount of airflow. Whereas....lbs/min will always be a clear indication of the power you are making and requires no other knowledge of the setup.
I always adjust boost until I am flowing a desired amount of air (which will translate into a certain amount of power onced tuned) and that is what I assume most people would be interested in doing.
