After some hours of driving, still a big smile in the face
Passat stage 1 is excellent work. The engine pulls direct when only tipping the accelerator. Pushing accelerator down it pulls straigt forward to minimum 240km/h, there was too much traffic on the road to check if more is possible. You can feel the turbo charger below 1500rpm (~1200rpm), before there was the turbo hole up to 1700~1800 rpm.
Verry good work!
