Hello, I’ve recently been a proud owner of a Saab 900 Turbo Bj 85. But since I know more about Audi, I have to ask myself a little cleverly… Is it normal that the turbo at Vollast will noticeably lower the pressure, and according to the display only goes up to 3/4 to the red area, or is it perhaps wrongly set? The air conditioning system works, just like the heater, not. I would like to expand both, but I’m not sure if it works with the air conditioning system m Is it possible? Come out of the room HH, and would like to have the turbo set at a “Saab-Fachman”! At the cold start it also doesn’t run right or always goes out (stand gas)… Can one of you give me a tip? Mfg Niko
