I'm a happy camper!!! Took my 300TD up Baguio, a mountain city 4,900 ft above sea level. No problems with power whatsoever.
Didn't have problems overtaking before the ascent... probably cleared much of the carbon making the ascent quite easy. Faster in fact compared to our 2000 F150 4.2 V6... Could actually feel the torque... didn't need to rev the engine much compared to the Ford.
