Had updated my maps during last weekend when Rajiv was here in Chennai. Now the low end torque has improved considerably. But the sudden bump in the boost around 2000 rpm is missing. Its more linear now. After remapping, tried Rajiv's Polo GT. It accelerates so much that the wheels spin (its a fairly new tyres which ran about 10k). The turbo kicks in as low as 1400 rpm. The gearshift is light and fast. But the steering is lifeless and Rajiv said that its handling is bad at high speeds. After driving Polo, I returned with a wish to get that engine in Linea.
