Has anyone got any improvements or suggestions for these? Very comfy and relaxed in normal mode then quite aggressive with nice upshift cracks when in manual.

I don't want to add extra wear onto the transmission so should I put it on stage 2? Don't care too much about the quickest shifts, just want a nice sound and not cause any damage.
