View Full Version : Anyone familiar with the 5th gen Legacy GT setup? I CANT FIND BOOST LEAK!

I have a vac/ boost leak somewhere. Its very odd because its such a faint sound that I cant trace the noise. I have a Cobb AP and Ive never hit target boost but now I cant even get close with HWG map sometimes. The EJ255 in Legacy GTs runs a higher compression that WRXs. I avg around 15 psi boost when target is 17 per Cobbs stage 1 map. Anyone have any suggestions?
