I wouldn't get too hung up on numbers from a chassis dyno. They vary alot from dyno to dyno and day to day. The only real use for a chassis dyno is real time tuning and maybe to do a to b comparisons on modifications that you can make within a short amount of time. I'd be surprised though, if your mods netted more than 10 real horsepower.

Looks about par for a 2002 Box S Chris:

I wouldn't get too worked up though. As others have said, high humidity and dyno runs do vary a lot from day to day.

Bonus question:

Do I get it right that my "sweet spot" for shifting up should be between 5.5k and 6k RPM?

Based on your torque curve I would use a shift point of 6K. Torque begins to fall off after that. Run to redline only when you need to extend a gear and avoid a shift approaching a corner. YMMV
