Overcammed 2.5L ?
Here is an example of a 2.5 L that we felt to be over-cammed. This 2.5 L came to us putting out decent HP, 183 HP @ the wheels, but, the torque at the wheels registered a measily 150 ft-lbs which is basically close to what "chipped" 2.3 L's can put out. The IS 2.5 L that we tuned was spinning the rollers to the tune of 167 rear wheel ft-lbs. We managed to use what we knew about these engines to find an additional 8 ft-lbs at the wheels at peak and more than 15+ ft-lbs in some areas. Again, this car came to us already with one of the more popular chips. We far exceeded that chips results. Tuning does work.
