i drive in normal traffic conditions, and rarely in peak hour traffic ( peak hour traffic maybe 2-3 times a year). thanks for tyre pressure advice and ecu,ill give it a try. however, im suprised with highway driving, i put on cruise control to about 100km/hr and i get 5L/100km!. When u guys drive hard and push it up to the redline for about 5-10minutes, can u smell some burning smell when the engine is off (coming out of the exhaust)? btw, theres never heavy loads and usually 1 or 2 passengers.
