NO, you should shift at 9k so you would land higher in power band in next gear ... look at the dyno, compare power you make in rpms that you land next gear to power at 9k
at 9k rpms you make 170whp, shifting to second you land in 6k rpms and only making 140whp... if you shift at 8.5k you land lower.

Something I prepared earlier - you can see the lowest rpm between shifts is 6000 in 2nd

For comparison here is a turbo shifting 700-800 rpm earlier

And same turbo shifting over 2000 rpm earlier

yes, I was trying to explain how to figure out best shift point - base it on power curve, has nothing to do with peak power ... as some who replied had no idea what they were talking about
I8U - your power curve + your gear chart with mph/rpms for each gear is the best/easiest way to figure out shift points
