By 2040 miniature computers have advanced to the point that Neural Computers are available to the everyday consumer.  Costing as little as a few day's pay or up to several month's pay, these implants allow a person to use the normally unused portions of the human brain for data processing and storage, though at various levels of efficiency, allowing them the convenience of a personal computer and cell phone without having to carry around a device for it.  Even the cheapest of NeuralComps (NC) give you several terahertz of processing power and dozens of terabytes of storage space.  NCs can also allow you to network with outside computers, letting you expand your capacity, interact with devices, or go into VR mode with others.
Soon after they were introduced, however, the NCs started to locate areas in the brain which, should they access them, would allow the user conscious control of their autonomic functions. and could even be used to enhance these functions.  Doing this would eventually cause damage to the body and brain of the user, however, so the manufacturers released an update to block this function.  Some people, known as Brain Hackers, can bypass those blocks and allow this function.  In fact, with only a few hours of research on the DarkWeb and a Bitcoin or two, you can purchase programs to hack your brain for you, allowing you to effectively buy superpowers.
The more you hack, and the more you use the hacks, the more your brain and body are injured.  We, as Brain Hackers, must learn this the hard way.

I don't care what your character can do, as long as it is an enhancement of or control over a function your body already has.  In fact, if you are creative enough, you might even be able to create a convincing explanation for actual super powers (amplified electrical current through a nervous system that has higher electrolyte levels gives you taser-like abilities, for example.)  Just remember that the more you enhance it, the more strain it puts on you.  Giving you conscious control over your heart rate or letting you go into REM sleep at will won't strain you much but controlled adrenaline output will stress you at different levels depending on the adrenaline levels.
