Checked with PL on this one since I only work the software/firmware side of things...

8 to 10psi is the answer for S13. The stock WG actuator spring gives 7 to 8 psi. But then there are two brass bleed jets hidden in the hoses that give you your actual boost level. The ratio of the two jet sizes determines the boost level – not the friggin solenoid

Stock boost is very hard to nail down cos you only need to fart and it’ll change. Have a look at the graphs for Graeme’s dead stock S15. All I did was tune the fuel and IGN maps a bit and boost crept up by over 1psi – no other changes. This proves that a stock S15 is 8psi though!
