I have torque pro, I can test stock Airbox and filter on lms93 tune and report data. If you want to do the same for Steeda's. I really don't want to return this CAI so I am hopeful there are real numbers to justify the 300 bucks.I can log via SCT x4 or SCTx4 and livelink. Can you run a base line for comparison? Since you have the experience with this it would help for me to actually see what you are logging for me to replicate.
