The stock WOT shift tables are 6200 RPM for 1-2, 2-3, and 3-4 - but actual WOT shift RPM was like 6000 for 1-2, and 6100 for 2-3 and 3-4 probably due to shift anticipation logic. I have datalogs at the track and on the street.
Are you actually seeing 7150 RPM for your shift points? Can you post some logs?
The final drive shouldn't require this high of a shift point.
