Interesting!!! So if the only hardware change to the N63TU is the addition of valvetronic, but that does not affect increase in HP, then technically, our N63s should be able to get the same gains as the N63TUs... through software.

I think it's time to rewrite those letters lol.

Does the valvetronic indirectly affect HP somehow? Boost can be increased through software but CR? Not sure. There's gotta be more to it than just the addition of valvetronic then. I think I'm confusing myself lol.
