Someone is watching too much Initial D
Wasted Spark is already in place on a FC.
And if you are getting what you think is a misfire/back fire in the exhaust at the exhaust manifold and cats, you are running too rich or have a problem with your air pump or ACV.

the pop is the extra fuel that is unburned igniting at the end if your exhaust when it hits fresh air with lots of oxygen.
if you still have a cat you might be able to pass emissions, if you don't, I would suggest leaning it out a little somehow (fuel controller?), or/and searching for vacumm leaks in your engine bay.

"Misfiring System" does exist. They are known as "Anti-Lag Systems" in real life. Some still call it "Misfiring" but not a lot. They are mostly used in the Rally, but is slowly catching on by the Japanese GT Championship (JGTC) in order to eliminate lag from turbos.

Yes, it is highly recommended NOT to have an Anti-Lag system on you car. Unless you are in a professional race, and your races are sponsored by companies then it will be fine, otherwise it will just be a waste of money to just try and maintain and buy new turbos to be fitted on your car.
