n55 vs n55HP - How do we get that extra power and torque?
I see that the N55HP has 13 more hp and 30 lb/ft torque vs the standard N55 in our F10. The N55hp comes in the 2012 and newer: F12 (6-series), F21 (1-series) & F01 (7-series).
Anyone know exactly how this power is achieved and if we can buy some OEM parts to obtain the extra power and torque of the N55HP?
