I thought it was a standard turbo as well. But when it was on the car I drove, it used to fly. I couldn't see no evidence of a boost controller, chip or anything. And AFAIK all the piping was connected as standard. It used to be 1 Bar but when the DET Sensor was changed, it went past 1 Bar.
The car used to boost past 1 bar for some reason and really felt fast. Any ideas?
