It's good to see you got it on the road. I have the guards red '77 930 that was at the body shop the same time yours was there. I have the same engine build but without the headers. It's fair to mention here yours is an SRD example. Nice car. I doubt the exhaust has anything to do with the over-boost, it's probably waste gate related. It might not have full range of opening. I tested mine on the bench prior to installation on the car after installing the 1 bar spring. I applied 15 PSI and it opened up. Check the vent side for dirt dobbers.
