Full Throttle, full boost hesitation revisited

[DGraber460 at aol.com]

Recently I thought I had found my FT hesitation problem in the FT switch. 
Running a set of wires into the cabin, I was able to confirm that the 
connection was made, and earliest results were positive.
The intermittent FT hesitation however is still there. I also played with the 
FPR pressure settings, and was able to change the running characteristics 
slightly with these experiments, but no major solutions.
The car requires peddle input to start cold, and 20 minute hot starts are 
difficult.
I have replaced the injectors, the O2 sensor, and verified outputs on all 
senders, and fuel pressure readings. A diligent scrutinizing with a 
stethoscope and flammable substances show no vacuum leaks.
All in all it's running quite well, just this one problem I'd like to cure, 
and I can't nail down.
Any input appreciated.
