Launched at between 10 and 15psi on the last run. Not sure of rpm but the launches were very uneventful. Just didn't want to break anything on my first trip to the track.
I am a big fan of the box. I would hit the switch once I left the line and when it shifted into second it would lock immediately. First pass I was so nervous I didn't realize I had already armed it, so I disarmed it coming up to the line, lol.
