Hi, have a problem with stage1 118d. The factory-set boost is 1.5-6bar at maximum load and keeps it like that, so the turbo is rather ok. After making stage1, the set values are 1.7bar and the actual 1.3bar. Up to some 50% throttle goes well and all values match above 50% the recharge begins to lose, I thought it was maybe because of a leaky egr, so I blinded it and threw it out of the ECU. I am uploading my file so that someone can see what is wrong with the maps and where is the problem..
