I have a 2002 cavalier 2.2 ecotec it has a Hahn turbo system on it but its only pushing about 2lbs of boost wondering if its supposed to build more or if that's right and how to adjust it I've tested for boost leaks and can't find any and replaced almost all of the vaccume lines? I've worked on cars all my life a little new to the turbo world though

Have you called HRC Tech Support? They are great guys to deal with.



I used to race cars, now I race myself.
