Thanks Bilaltq, bro. My car is an excellent drive, engine is like new both from inside and outside, most people who open my hood, get pretty wide-eyed by the look of the engine bay! The damn thing shines like new! Body is even better, in British green and interior is like new. I will post some pics tomorrow. It has only done some 6 thousands on CNG. My point therefore is, why cant this thing go any faster? There is no tuning problem, because pic is excellent, both on CNG and petrol, it beats most similar VTI's even, because engine is like new. Yet at 160 it seems to get tired, and uphill meter starts coming down pretty faster than it should, stabilizing easily at around 130?
