6700 here. I was shifting at 6500, but 6700 provided slightly better results. Sometimes I wonder if I should go back down to around 6500 though, that slight improvement could be causing more stress on the engine than I realize.
6400 RPM shift points, 6600 RPM limiter here. Car peaks at 6200 RPM but from 6000-6400 RPM it carries basically the same power (335rwhp) through that whole section.
Interesting too, my shift extension is 5,000-5,200 RPM and the car has over 325rwhp from 5,000+, so after I'm up and rolling the car has a pretty smooth power delivery. That makes me very excited to get to the track and see how it runs, especially compared to other 335rwhp cars in the traps due to my area under the curve.
Take notes try 5500 6000 6500 I did this with mine and found I was getting the same times shifting at 5500,so save your motor, I have not been to the track since I did a bunch of mods but not it feels like we are pulling hard through 7000 now, but that is in the big bang range.
