In many cases, bad fuel quality is the reason for stuttering or spitting engines with a dme tune.
I don't think, your hpfp is the faulty part in your setup, but the tune itself is. Bet, you have to check the fuel-flow map in your file. Seems like it asks for to much fuel in the mid-range. A less aggressive tune with a more linear increase of boost pressure to higher rpm's could already solve your problem.
