Okay I agree the 39 HP is a wrong figure.
What about no noise issue in the Japanese AGS? AGS in not a translation it's just module attached to a manual gear box. The only noisy transmission known is CVT
About using regular fuel, I have been using regular fuel in all my JDM Vitzes since 2006 I have had no issues with fuel usage. So that's definitely not a problem.
By detuning the engine I am referring it to be adjusted to Pakistan environment.
You see mehran is a pathetic car but it takes leads against any 660cc dinky with a CVT transmission because of it being a manual and having a good pickup. And can cross the steepest slope while a CVT cant goto such heights atleast a 660cc cant make it.
Similarly Alto makes noise because the engine reaches hi rpms at very low speeds. This is not the case with the Japanese variant. I have traveled in alot of careem jdm Altos ags and CVT variants. The drive on the Japanese car is alot smoother then the Pakistani car.
Iridium and copper sparks plugs major difference is change interval.
They suzuki Pakistan are trying to keep costs low. So maintenance stays as cheap as possible.
