Has anyone fitted this to their subaru, if so:

1 Did it work ok.
2 What psi, is the limit for a 02 wrx sti ppp.

I have a psi gauge and it boosts at around 17psi (i think).

Find IN CAR BOOST CONTROLLER SUBARU IMPREZA WRX/STI on eBay within, Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (end time 31-Oct-07 09:17:08 GMT)

I did have one fitted onto a vw golf gti turbo, def raised the psi and gave the car some oomph, i know a subaru is a different animal, but i guess the principle is still the same... or is it?

 

Get a proper in car electronic boost controller like a blitz or HKS or Apexi.
Bleed valves are very crude

 

That's a bleed valve. It will increase the boost though not by the most ideal method, removing some of the signal air to the wategate. Better to use an electronic boost controller, or something direct like a dawes device. Best still get it re-mapped properly then you won't have to worry about blowing it up!
