Hmm .. so that means it doesnt have limiter and even if it did, it should go above 150km/h just like "Mafzaltareens" and dude, wait till u get on the coastal highway , even 160km/h on a straight smooth road would not feel much
@Akif and Mafzal and Javed
How does your car go above 130km/h, mines automatic , and doesn't removing the cat increases the fuel consumption ?
Could be something to do if u have CNG installed, if they dont fix the wires correctly in the MAP sensor the OD doesn't work. and about the pick up .. please get ur throttle body thoroughly serviced/cleaned, plugs changed and the rpm (if only on petrol) should not increase 600, would give u a good response
