Seems like the guys at Rica are pretty busy at the moment! I just called to make an appointment for this week, but they're fully booked up until next week. But then my car is in the garage for a big service next week, which means that I can't take the car until the following week! So unfortunately it's going to be 3 weeks before I get to the dyno!
But there's plenty happening in the meantime... today the car is having it's APK (road worthiness test... finger's crossed that it passes, in particular the emmissions test!), the new wheels should be ready for the end of the week (although I'm suspecting that it's going to be the following week) and like I said above, the car's in for its 60k km big service next week!
