Ok, vehicle is back, and repaired. Here is the breakdown.
The vibration on accel between 1600-1900rpm turned out to be due to the L/F CV Axle. The splines on the axle that go into the transmission were worn down. This caused a reverberation at this rpm. All the computer sensors in the car then tried to compensate and it felt like a transmission or injector issue. Since the CV Axle was replaced, the vibration is gone and no matter how hard I try, I cannot duplicate it.
