My car:
1999 Toyota Corolla GLi 1.6L A/T
engine mods: cone filter, headers, 2.25in exhaust piping, low restriction aftermarket catalytic converter, custom design full stainless freeflow muffler.
Wheels: 195/55/15

LPG system:
NAIADSS carb type LPG kit with EFI adapter box.
Tank size: 60L

Fuel mileage:
City: 5-6km/L (a/c on)
Highway: 8-11km/L (a/c on)

So far the car performs well, overtaking is not a problem. Top speed achieved is about 165kph which is roughly the same when fueled with gasoline.
