I have searched all the other low boost threads but not found the answer to my problem.
Basicaly my 9-5 aero boosts 75% into yellow and dosent reach the start of the red untill around 4k rpm when it reaches the start of the red there is a noticeable increase in power.
having watched videos on youtube it appears it should reach full boost much quicker than 4k rpm
I have tried blocking the top pipe on the evap valve which made no diffrence.
i have reset the ecu which again made no diffrence
i have no cel lights
car was serviced a few months ago using genuine saab parts.
other than the low boost it runs perfectly fine and it does eventualy reach full boost but not untill 4krpm, the car is run on shell v power.
i dont know what to try next i cant hear any leaks as i have an open airfilter.
its really bugging me now any ideas what to try next?
