I'm using a Works BOV which is basically factory with a stronger spring. It was fine with the stock turbo but now this ball bearing GT30 just pumps too much air at light loads and the BOV is fluttering and not reacting quickly enough. |
Why are you driving up a hill with load on the car in 5th gear ?
