brixton crossfire 500 tuning for smoother midrange and less guessing

I am helping with brixton crossfire 500 tuning on a bike that feels a little snatchy off idle and flat in the middle. The owner wants exhaust and ECU parts, but I want checks first.
I found this related page while comparing notes: brixton crossfire 500 tuning. I wanted a practical thread before ordering parts.
Would you check chain slack, throttle free play, air filter, plugs, intake leaks, battery voltage, fault codes, brake drag, tire pressure and a same-road roll-on before changing parts?
