Hi
@ Rob
The Throttle Body bring a little more Power - not much!
In germany cost this 100€!
You can change the Boost Sensor in the Digifant Motor Management and take a smaller Pully(65mm)!You can also take a bigger Air Cooler from the Golf 2!
Iam at the same Point like you - i take yet a Lysholm Kompressor!
Regards Thomas
