Thanks G for your response.
I do agree, there is a lot to smile in the current motor. It's not just the sport button, but last time i was driving on the highway, i noticed my avg mpg for that tank was 28.6 mpg...it was amazing..only Lex\Toyota can build such a good balance.
At times i do wonder about what it would be like to have a higher torque cutoff. I was watching the video of the LF-A the other day and that engine seems to be a beauty as it loves to rev high up.
Wonder if anybody will tune the ISF engine to deliver higher. Will a lot of the internal components from camshafts to valves, have to be strengthened?
