E30 Rb25 Setup Issues

How do I lower my boost? I have ecu manager,

[Timcgt]

So ive done a wee bit of research and apparently its not as easy as just dialling in 15psi....

so to get me out of trouble and a temporary fix i will run a vac line direct from the fitting just after turbo to the wastegate actuator. i have a knock monitor on the way but dont think it will be here by the weekend. hoping it just runs a bit rich over the rev range.

i might turn on the knock correction in ecu manager and go for a squirt and see if it drops any timing....
