A quick guess would be that with the clamp mod, you are increasing your HP oil more than you would with the 10k. THe older 94-97 psd's have a lower capacity HPOP and at the higher RPM's you may be running out of sufficient oil volume/pressure to maintain that level of injection. I would try putting a 1k-5k potentiometer(variable resistor) in line with your switch and adjust it to the point where the problem resolves itself.
