First of all, hello to everyone and happy holidays. Hate this to be my first post but it's really bugging me and since the official dealer won't be opened for a week you are my only hope.
Now about the problem. Two weeks ago a bough 2010 RCZ THP200 at 102k km. Drove it for 250kms then went straight away to the dealer to do the maintenance. Since I was not sure about the drive belt condition and any hidden gremlins I really didn't push the car to high speeds and high rpm acceleration. At the dealer the drive belt was changed with the tensioners, oil and filters, coolant, new sparks and coils. Basically I told them to do full inspection and replace anything if needed, as they did.
With all thing above done, I made over 1500kms of driving for less than a week. Really love the car, the handling etc. you know why we love these cars. Anyway, I noticed that when I really push it over 3500-4000 rpm , wide open throttle, I feel like the turbo isn't really kicking in. To explain it better, the acceleration from 130 to 170 would be almost the same no matter if I do it in 4th or 6th gear.. At low rpms I really can feel the boost building, but then at the higher rpms it's like vanishing. Don't get me wrong, the car still goes fast but not as it should go, especially at higher speeds. I'll leave link below for acceleration video to check it out. No strange noises, or engine idling problems, sputter etc. nothing. No engine lamps and no codes read at the dealership. I had similar problem with my old car which turned out to be the turbo actuator (the spring had gone soft, leading to low boost pressure). Did some research here, but couldn't find anyone with the same problem ( or my research was lame) Any thoughts on the subject would be much appreciated.
