The turbo on the car is what came with the car, it's not aftermarket.
I literally just picked this car up brand new yesterday, well petty much brand new. It was test driven twice with a total of 80km on it.
Twice now I have noticed that after driving for a little bit, like maybe 10 minutes, the acceleration of the car isn't the same. For example: From a red light going green, pressing the gas you get a real nice boost (Not flooring it) and you really feel it, but after about 10 minutes (Not every time, this has only happened twice, and the 10 minutes is just a guesstimation), pressing the gas the same amount, you don't get that boost or feeling of acceleration. Not only from stop to go, but even when trying to speed up. It felt sluggish.
Before anyone asks, I was not on a hill.
All of this is also without having it in Sport mode and not using premium fuel. The car is still using the fuel that the dealer filled it up with.
