| Your "spool" will be different in every gear. Is the onset of positive boost at 3000 rpm or do they hit peak boost at 3000 rpm ? Also what gear are you measuring this in ? As an example gt28rs on my car make positive boost at 2000 rpm in 5th gear. That does not mean they spool at 2000 rpm. They also hit 15 psi at 3100 rpm in 5th gear FYI. This is different in every gear. You need to be more specific with what you are saying.
