The new BMW 7 Series model, the LCI version if you will, comes with some heavily revised engines. One of the biggest improvements comes on the 750i model, which still uses the N63 engine but now delivers 530 HP to the wheels. That’s because BMW decided to offer the same engine on the 750i as on the M850i model and that makes the flagship sedan quite fast rocket on public roads.

Of course, some customers weren’t happy to hear that. Most of them were owners of the pre-facelift 750i which, even though it uses roughly the same 4.4-liter twin-turbo V8, comes with ‘just’ 450 HP and 650 Nm (479 lb-ft) of torque. It’s not a slow car by any means but the new iteration of the N63 engine does provide more grunt than ever. If you’re such an owner and you’re wondering what you could do about it, fret not as some tuners have a potential solution.

The guys from BR-Performance in Belgium have announced a Stage 1 upgrade for the BMW 750i which not only catches up to the latest version of the N63 engine power output but also kinda overshadows it. Their upgrade takes the power output up to 550 HP and 820 Nm (605 lb-ft) of torque and those figures are better than the 530 HP and 750 Nm (553 lb-ft) of the updated 750i. As for how that translates into real-life performance, it remains to be seen as the tuner didn’t provide such info.

Nevertheless, what’s interesting is that this impressive performance increase is apparently achieved solely by re-writing the software on the ECU of the car, without any hardware upgrades. Whether that will affect your warranty depends on a number of factors so you’ll probably be better off with the standard, facelifted BMW 750i if you’re looking for a luxury sedan with over 500 HP.
