Test drive went fine: clutch engages really not different than the former one, which is great!
Backpressure is about 50% over boost pressure, which gives great spool but seems a little too restrictive for this 2.2 liter engine.
I need a bigger turbo!

(again..

)
Next weekend is Spa Francorchamp 'Le Bug show'! Can't wait to finally be allowed to drive the whole track.
