I havent had the money to fill up yet. It wont be accurate anyway as i did the eco trail on the last tank. Then again the range seemed to have been the same with the eco trail included so i suspect the economy has improved.
I can definitely feel the extra oomph from idle up to 3000rpm. From there to redline its hard to notice any difference. I dont go there often anyway. The low torque is addictive especially in 3rd and 2nd gear!
