Well sandro, I have this problem all the gas pressure before I go up a lot, about 1.7 then descends again to 1.4 then to go back and stabilize at around 1.6 all in a matter of seconds. Now I would like to try what you have written you to decrease a bit of an overboost to try to have a pressure pi? stable without the piccata cos? high. How should I act on the map? I'm from the met? by selecting all the values and set them low of 3%? Considering that the maps times ing. and turbo I have changed from the met? load.
