If u make a change to exhaust system or change  , injectors, intake air flow,” any change” does your computer remember the old way it was running and get confused w/ the new changes u did for a while and run ruff. Should u reset computer to start fresh.? If so what’s the best way to reset I have heard all kinds of ways to reset ,pull neg off battery,pull pos.off first . Pull fuses , remove left front tire turn on key 3 times , which one is right and does it reset instantly to normal operation or do u have to  Cruise around for a while

Keep battery hooked up. Turn car on it&rsquo;s roof. Shake aggressively 3 times (if shake 4 then you will have to start all over so b careful)
Put back on its wheels wind it up a bit, then let it go!
Reset and manual tune! Better than new!
I usually add nitrous oxide at this point so my and your results may vary.
