It might sound strange to be worried about it - but, quite suddenly my car seems to have a lot more "oomph" from out of nowhere. It started when I was getting on the on ramp a few months ago. It seemed like the car was able to produce significantly more power, and it now cuts the power quite suddenly at a certain point.
This is a completely stock 2006 Volvo s40 T5 (turbocharged) with a manual 6 speed.
Can someone explain why this happened and should I be concerned about it?
