fitted my bleed valve the other day, would 15psi be a safe range for the engine to run at or could i go more or should it be less. can anybody help?? thanks if you can.

 

What MY is the car? Is the car UK derived or a Jap import? When raising the boost it is advisable to fit a Knocklink and a Lambdalink - both shown HERE (about a 1/3 of the way down the page with descriptions) The Knocklink being most important as it will give indication of Engine Detonation which eventually leads to engine failure

Cheers

 

it's a my99 impreza uk turbo
