dat111 Posted April 25, 2022 Share Posted April 25, 2022 (edited) 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?

Roland@pcmtec Posted April 25, 2022 Share Posted April 25, 2022 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. 1 Quote Link to comment Share on other sites More sharing options...
dat111 Posted April 25, 2022 Author Share Posted April 25, 2022 should have mentioned. its a NA+t running gate pressure, with a full stock turbo dump to tail pipe end. Quote Link to comment Share on other sites More sharing options...
