my 2004 wrx came with a blitz turbo timer on it - one facility is the monitoring of the boost pressure. I have tried it out and just on a short run with a brisk acceleration it came back with a max of 1.32hkpa.

this works out at around 19psi (I think) which led me to wondering what is the max boost pressure for a stock wrx ?

I`ve searched the net but got a whole range of different answers - although one prodrive test said it max`d at 190kpa.(27.5psi) ?

last turbo car I had was a fiesta turbo back in nineteen canteen so I`m a bit out of touch.

thanks for any help or insight you can provide
