Interesting!

Do you know your Intake Air Temperature at 28PSI? How much Ignition Timing are you running at redline and how much ignition timing is pulled back if you stay longer on the throttle?

Do you have the possibility to measure your Speed (160 MPH) with GPS, e.g. Garmin?
23 sec. for 0-160 MPH is not bad...

Good luck with your Project and stay safe!
