Hello, with my T5 I noticed that with a DZ of approx. 4000U a slight kink occurs, a short hold of the charging pressure and then goes on. It is not a sinking, but only a small plateau (at approx. 0.75bar). It happens to me that the phenomenon is less pronounced at temperatures below 22°C. But with the popometer the feeling of a small power drop occurs. * No fault in the memory. * 98 OktanWhat’s new: * Candles * Air mass meters * Cam wave adjuster What can this be? In the appendix: horizontal line on the ordinate on both diagrams: To constantize the values I drove for a time with the tempomat to ensure the stabilization of the ignition angle and the charging pressure. Then from 3000U I started to pull through as the starting rotation number with the third. After that accelerated up to 5500U. Right yellow line at x-axis at just 3″ (time in seconds): Small break-in. You can see it also with the ignition angle curve, that what changes there. But according to T5 the driver has always been a similar characteristic.
