Well the dv valve made a big difference, now new rubber on the front, a new thermostat and a pcv valve and it's a new car again.
The tyres are Vredestein satins which are dead quiet and grip like mad and have stopped a lot of wheelspin.
The engine heats up to 90 very quickly and the power delivery is much smoother.
I might not even get it mapped now.........or should I?
It is so much more fun than when I bought it a few months ago.
