Good day, I became such a thing that when the 4th and full throttle subsided my car and as if I lost part of the power, after making the log of UpRev I found out that AFR suddenly shows the values (no load 1.5-1.3) and (In a load with a rising speed of 0.3-0.1) I'm already crazy about it and I do not know where to look, we have passed the whole line from the compressor to the suction and there is no escaping pressure anywhere (the pressure on the wheel looks good on the alarm clock) According to the AFR alarm values, it seems to me that the amount of air at the same time was smaller and therefore a rich mixture. The compressor propeller is OK and without the vultures we have already checked. Before that, AFR was OK, at WOT 11.5. Has anyone solved this problem?
