Is there a a higher performance hpfp for the m2 yet?

boost is actually hitting its targets. boost pressure at the throttle is at the target even though fuel pressure drops.
there is a pnp hpfp being developed and some other company is currently selling a kit to retrofit the dual pumps from the s55. both will require custom tune.
