On the n55 cam profile using dorch engineering's numbers yes 7% is the calculated value. Looking at data points from other B58C pump users there is an improvement but logs show an hpfp crash with only a bit more ethanol or boost vs. the stock n55 pump.

It's no where near plug and play, you have to do alot of modifications and you have to Dremel the bottom of your intake manifold. Imo I wouldn't cheap out on an hpfp. There are better places to save money like intakes and downpipes.

You should do alot more research on hpfps before deciding which route to go.
