Just FY(F)I, your post is based on ULTIMATE stupidity.
You say "tooning"... Okay let me explain tooning to you, are you aware of carburetors? They needed tooning, a different one, like distributor cleaning, throttle adjustment, fuel mixtures, timing, bla bla bla.... The list goes on, I don't know crap about them as I never observed a carby vehicle.
Today's car's are different, they're EFI engine powered. They have "throttle bodies" and a vast array of sensors and an ECU, almost identical to a humans nervous system. Just that the role of "effectors" is somewhat still assigned to us, human beings, a very little part of it is controlled by the sensors themselves.
Whenever there is a change in any of the sensor values, the other sensors act as to nullify the effect as far as possible. If its beyond their level of adjustment, they send error codes to the ECU which then displays error specific warnings in out instrument clusters and EBD scanners.
This wasn't the case with carburetors which needed thorough manual diagnostics to pin point the problem, EFI cars simply tell you where the problem is, and once you kill the cause, they return to their normal operating states.
They still require tooning. And as of what I know, at the moment there is NO carby vehicle being manufactured is a PKDM.
Therefore, agha waqar ko copy na karen by saying "JDMs tooning appay kar lendyan ne".
All cars need throttle service, tappet adjustment, valve clearance, fuel pump/filter replacement, injector cleaning, sensors' maintenance/cleaning etc on regular 20k/40k kms basis.
I own a PKDM, mai koi ni le k jata usay har 5k kms par "TOONING" karwanay. Its been 65000 kms since the tappet cover was opened. In the Corolla, nothing has been opened except for the stuff involved in regular maintenance and the black thing housing intake channels (which reads 2NZ-FE can anyone specify what is it called, @SER_GTR), because back fire due to CNG advance tore a membrane sort of thing in there.
Its been 200 thousand kilometers 
Now praise used and abused JAY DEE EMS like souvenirs from the Japanese specially for Pakistani brothers, because they've got nothing to do except to buy cars, kiss them day n night and then export it to Pk.
Grow up and accept the fact that they're just as used as any other PKDM vehicle, made in the same way and sold in the same way. The only positive is the several features included in them, nothing else.
