93 wrx overboosting (quite a bit)
basically a mate has a 93 wrx and its hitting 1.5 bar,pulls like a train but the engine isnt likely to last long like that,what could cause that to happen?I thought it would hit fuel cut way before that

Sounds like a boost controller of some sort and/or a Fuel Cut Defender has been fitted. Any more detail?
As MBW says a standard fitment ecu should hit fuel cut much earlier. 11.47 psi = 0.8bar, 14.57psi = 1.0 bar.

everything looks normal,he bought it with the boost problem and got it cheap as a result,but there must be something preventing the boost cut from happening and maybe stuck wastegate or problem with the boost control pack
