You should be shifting just before limiter for maximum acceleration, 6k is far from when you should be shifting. Peak hp is meaningless. You shift when mechanical torque at the wheel in the current gear is less than mechanical torque at the wheel would be in the next gear you would be shifting to, typically this rpm however is beyond even the limiter so we are limited to the rpm of the limiter before shifting.
Thanks for the reply. Sorry I am confused. You're saying I should be shifting at around 7k RPM (assuming redline is around 7.2kRPM)? My torque and HP are highest right at 6k RPM; if this is the max in the current gear, how could the torque be higher in the next when I am upshifting?

That's where you meet it. You feel it coming. It creeps up on you, close in your ear. Asks you a question. The only question that matters. Who are you?
