Who is the best EFI mechanic in Karachi?

I have Toyota Passo 2017. It is giving very low average almost 7. And it loses power after driving in traffic jam for 10 mins.

I have done every thing.

Plugs change
Gear oil change
Engine oil change
Tuning.

But not working at all.

Sounds like someone has tried to “tune” the engine too many times by “cleaning” the maf and AFR sensors etc.

Or it has a failing battery or alternator.. (does it start to misfire at near to redline rpm?) Does the engine pull with all its torque in midrange?
