Fred, the engine does not stumble when turning left, only right!!
My fuel pickup is on the drivers side bottom of the tank so a right turn would push the fuel to that side!

You only started having this problem after the dyno tune if I am reading this correctly. Is this the first time you have gone through having it tuned and then set back after the smog check? If so, then I am guessing you never had any problems before after they set it back for maximum performance. Is your fuel pump mounted on the left side or near the center of the tank? It is possible, but not likely that it could have a little crap in the filter and on right turns not pull enough fuel into the lines to keep the car running for a while. If you have a fuel pressure gage watch it and see what it does.

Float material???
Terry - this sounds very familiar!
What material are your floats? Are they the old brass cans, or are they the foam composite material as shown in a photo on this thread? If they are the plastic/foam/composite type, they may be going "soggy" on you, losing buoyancy and causing a super-rich stumble.
Some of the foam composite floats that Carter used in the 1980's got a reputation for this. Over time, the gasoline & various additives attack the material, soak into it, and make the floats heavy. One of the first indications in many Dodge trucks & Jeeps with the Carter BBD 2-barrel carb was a flooding-induced stall during hard turns (I think it was left turns on that model carb).
Just a thought!

Thanks for all of the suggestions guys, I am taking notes!!
Ron: The fuel pump is on the drivers side right by the tank fuel outlet and I will check to see if there is any debris in it again because I cleaned it out last year when this problem developed. This was my first time have it "detuned and then tuned" for emissions!
Zach: The carb floats are brass and they are empty!!
Thanks again for all the help!!
