With 5k miles up and the engine loosening nicely I decided a trip to Red Dot was in order to liberate some more horses and sort the sub 2000rpm torque dip.
What a revelation
Previous numbers 184bhp @ 3500rpm/260.1ft-lb @ 2400rpm
New numbers 225.3bhp @ 3300rpm/314.6ft-lb @ 2600-3200rpm
Now the car feels and goes exactly like it should - pick up from standstill is smooth and that torque curve is just
For less than 1% of the cost of the car it's added 50% to the enjoyment - now it doesn't just look

it goes
