hey all, just brought a turbo for my car. 
 from my googling it suggests its a 6psi replacemen, according to GCG turbos website. .  but its off an FG f6 turbo. 

its the wastegate controller that it the factor that determines the wastegate pressure between all the cars is that correct?

It's not quite that simple. Backpressure affects the actual pressure quite drastically. So even if it's a 6psi spring doesn't mean it will run 6psi. Also the controller will have PID gains that are tuned for a specific turbo combination. As soon as you change anything at all, these gains may cause over or under shoot of the boost target.
