Meal Community, What does your experience look like in terms of performance improvement on VEA engines. My V70 (’16) VEA D4 has a Polestar performance optimization (181PS/400Nm -> 200PS/440Nm) at 237tkm. I want to make life a little easier for the engine on its old days and “optimize” the AGR. With VDASH such optimizations are no problem, so I decoded / unlocked the ECM and CEM and wanted to “optimize” the AGR now. In the user interface, however, I now only follow The possibilities:1. ORI + EGR OFF (133-kW Power, 400-Nm Torque) 2. ST1 + EGR OFF (156-kW Power, 440-Nm Torque) In principle, I would like to keep the Polestar optimization and only optimize the AGR.But if I now choose the 1st option, I lose my Polestar software, or is only the AGR “optimized”? I could now also choose Option 2 and enjoy the 17 HP extra power, but I am satisfied with the Polestar performance. I have already contacted the D5T5 helpdesk. I have already written to Mr Motl about this forum. Unfortunately, I have been waiting here for almost 4 weeks for an answer. If possible, one of you also has Stage 1 on his VEA and has already been able to gain some experience here? Advantages/disadvantages?
