Thanks!
If most of your driving is around town try closing the butterflies (and balance if that's open) by moving the brown arm all the way to your passenger side (closed) the car should then be at max torque at 2700 rpm (2.0 & 2.5). In the medium range the power vis should still be closed but the balance open, now the peak torque is at 4000 rpm for the 2 ltr (3750 rpm 2.5).

The power vis only really comes into action after 4000 rpm - 6500 rpm (2.0)
