On the contrary, you should be impressed with an engine that can get so close to 400 hp with only a "mere" 5800 rpm. Other smaller engines need rpm to hit numbers like that. Ours does it with brute torque.

I can understand your motivation to change the shift points to unleash more rpm, though. Fwiw, I don't think any additional hp is really there to emerge as you extend the rpm, anyway. On top of that, I don't think automatics are all that compatible with high rpm. I suspect fluid drag catches up with you, the faster you spin it.
