Boost and knock problems 84 hairdryer

[GN84Driver]

I have a problem with the boost varing wildly after the car reaches 5-6lbs of boost. I still have detionation problems even with booster added to Sunoco 94. Any information would help.
Thanks, 84GN

can you be more specific?

Check fuel pressure, maybe the fuel pump is bad.

May have bad injectors

Those are the two things that come to mind, with the info given??

varying boost and detonation

Thanks for the input. I will check the fuel pump and injectors. I'll let you know what I find. GN84Driver
