1979 Porche 911 issues

Hello fellow Porsche Enthusiast. I am hoping someone can shed some light on the problem I am having with a 1979 911 turbo I am working on. The engine is sluggish and stumbles up to 3000 RPM then she takes off like a rocket. I have checked all the vac lines for cracks and replaced suspect lines, I also have checked the waste gate for problems. the gas tank, fuel lines and fuel pump have been replaced and I am still experiencing the same problem. A little more information on the problem: The stumble occurs at full throttle, it feels like you are hitting the rev limiter, if I back off the throttle a touch she makes it up to 3000 rpm then its bombs away. Also at higher RPM when I let off the throttle she backfires a bit. I am running out of things to check.

Has anyone had a similar problem and what was the solution.

Any insight into the solution would be greatly appreciated.
