I can never figure out when either the turbo will kick on, or has kicked on. So, I think a turbo light on the dash would have been useful. I have had this car for 8 months, and I still cannot drive it effectively. When I mash it, I dont feel as much pull as when I barely give it gas at 30 miles an hour and it pulls itself away noticeablely, and almost always when I dont want it to do it. There is definitely a power band, but I have yet to find it. Just a frustration. Maybe by the time I sell it, I will have figured out how to drive it. It almost seems like the only way to ensure the turbo will kick in predictably is to use the paddle shifters and downshift a couple of gears and then mash it. Dunno.
