Sounds like the go.

It will be great to feel one of these boost u to 16psi or so.

Max ive ever had is 10...

We knew which pins to swap, they were the right way around. We started the car to confirm the fuel pump wiring pin, immoblizer or non immobilizer. It's easier to do one thing at a time instead of 2 and not know where you're at.

Your BCS hoses have been played with, The large diameter hose should not go directly to the 'T'. There's usually a reducer in there that someone has removed, and the T is not the OE part. I'm reluctant to increase boost levels as the intercooler has had all the fins flattened and the fuel pump is an unknown quantity.

PM sent,

Im happy if we can just get it to run at stock boost 15-17psi for sti??

Ill get the fuel pump etc all done at a later date, as long as i can get it to run good now.

But Doug is running the car safe as your intercooler isn't worth a shit with the fins blocked therefore lowering boost because of hot air intake temps and the fuel pump could allow the car to run lean until you either know what it is or upgrade it, best take his advice.
