MDX Hybrid performance upgrades?

I am loving the MDX hybrid and the way it drives. I gas up maybe once a week. honestly, sometimes I don't even remember when was the last time I went to the gas station.

The car performs very well and sometimes I am shocked at how quickly it picks up when trying to pass someone on the highway.

I wanted to know if there is anything out there that we could do to the hybrid to make it even faster? Like more powerful motors, ecu tune, etc.. I am still new to hybrids so I do not know if this will mess with the hybrid driving system. I also know that if there is opportunity to increase performance, gas efficiency will take a hit.

Don't get me wrong, the sport hybrid mdx is no slouch..

Any insight would be great! Thank you.
