dear brother i am from Multan, modified khyber with vitz engine auto transmission, car is good, pick is good, easily go upto 140KM/H, fuel economy is good 17 km/L without AC in city drive, but in rush hours on apply to much brakes problem started. its vibrates very soft, not hard, and if i dont race it or switch neutral mode, engine tends to off/switch off on the road. Meter is semi modified of khyber, so dont show any rpm. but at idle drive mode car rpm seems normal, not seems race or high rpm, when first time vehicle start / switched on, its rpm tend to increase but after short while it become normal.
