Wow - Thanks. More detail as below:
Here is an example of what happens...
I will be driving along a road and will come up to a slight hill. I start to give a bit more fuel, and the boost gauge will start to rise. (If I floor it, I can get the gauge to shoot up to the max mark and it does not go past it) The car will start to pull and I can here the turbo start to sing - and it may run fine for 30 seconds or 2 minutes - and then Whoosh - BOV opens and boost drops. When it happens, if I keep my foot flat I can here it blowing out of the Valve. If I back off, it will close and then when I start to acc again, Open it comes again. This does not always happen, but seems to be if I have been driving for a while. Temp is OK and it will do it if hot or cold.
I have not changed any thing on the car and it has been doing it for a while.
Fuel wise, I use Premium fuel.
Car wise, I have standard setup, only changes are 2.5" System and Pod Filter.
Thanks
