Hello saabers
so my 01 9-5 2.3t is only boosting at in the middle of the yellow. At first I thought it was the evap system or one of my check valves so I did what chris 9-5 explained and plug the top hose that connects to the top part of the boost controller. That only fixed it for a night. Thus I noticed the pcv breather nipple broke off, hose leading the check valve (crank case vent system) so I fixed that and still only boosting to mid yellow at 2500k -4000k. After that it boost all the way but seems to be struggling still. I doubt it's my cat bc I just got a custom 3 inch full exhaust with magnaflow cat and muffler.
I don't hear a hissing so I also doubt it's the brake booster but I'm not a full saab master tech.
My upgrades
stage 1 ecu
air intake
3inch dp and exhaust. Cat and muffler
Changed a few vacuum hoses but haven't touch the evap system or crank case vent system. Any help is appreciated
