Here is another graph showing the actual boost output from a S4 with a modified 3 Bar ECU, using the RS2 Exhaust Manifold, and the RS2 Turbo. Vehicle has the stock exhaust system with catalytic convertors.



The actual boost output will vary somewhat, depending on the air temp, fuel quality and altitude. The graph was obtained using an electrical pressure transducer, and a portible Oscilloscope. The small rough peaks on the graph, are caused by electrical noise on the Oscilloscope trace.
