some of us have grown up with high revving NA engines whose power increases with RPM, which makes the current generation of turbo cars feel very dull and very artificial to drive. If I wanted loads of boost and loads of power at 2k rpms I'd buy a diesel, I like a curve to climb with RPM for driving enjoyment, a very broad and flat curve just feels boring to drive.
I feel the same way... here is the torque curve for my turbo car (2006 Volvo S40):
Lots of torque coming on very early, but not all that fun to drive IMO.
I like driving a manual transmission... I like the directness of it. My turbo engine with its small but perceptible lag gives a less direct feel... Response from a N/A engine is instant, not time dependent.
Looking at a "Tune" for my GS when the warranty expires, not looking to race or abuse the car but improve the performance and unused potential of the engine and tranny.
