We are proud to offer a game-changing product for the N55 community! With this innovative solution we are able to add up to 49% MORE fuel flow on top of either one of our existing N55 HPFP kits. This means higher power capacity than ever before possible with the OEM direct-injection fuel system. We start with Genuine BMW vacuum pump cores and install our Dorch Engineering Cam within the OEM assembly using our proprietary manufacturing tooling and validation equipment. What you end up with is a ton more fuel flow in a very simple and clean package, all while utilizing the safety and sophistication of the stock DME. These are never before seen DI power numbers!


When combining the N55LK with our DS25 HPFP (or DS2), it is important to note that there is a minimum power requirement. This is simply to ensure that your vehicle can easily be tuned and operated like OEM. Going below these thresholds makes your tuner’s job more difficult than it needs to be. With the DS15 HPFP on the other hand (or DS1), there is no minimum power requirement so it would always make sense to use the +49% N55LK in combination with our DS15 (or DS1) HPFP.

Software changes are required to run this upgrade, but we do have preset optimized maps available via Bootmod3 and MHD (coming soon). Simply check the box for the appropriate “Lift Kit” upgrade when flashing.

NOTE: When pushing much beyond the flow capacity of our existing Stage 2 HPFP kit, the N55 is very much limited by the injectors. In order to see the full potential of this upgrade, it is highly recommended to upgrade to the larger S63 EU5 Injectors. These are OEM BMW injectors that flow up to 800whp on full E85.

Fantastic price for such great value
Love love this vacuum l!!! Love that it’s easy to find replacement parts and for every part you’d need. It does a fantastic job mapping out the floor and rooms. You can see where it’s been on the map and if you’re mopping, that feature makes it great because you know where you can go ahead and mop. It’s SO MUCH QUIETER than the Rumba and the Shark brand. It gives you the option to select rooms that you want vacuumed without having to do all rooms, it does use a bag and that concern me at first because I didn’t won’t to buy bags. These bags last for a few months at a time and I’ve got an indoor cat so that means lots of hair. It does an awesome job going anywhere it needs too and does great at picking up. It’s not large size base and fits nicely in a one foot area. Over all I would definitely recommend and buy again from this company, the price and value to me is way better than the other Big Brands.

Replacement parts
I wish this package included an extra dust bag or two. I wasn’t paying attention when I ordered it alongside my new Eufy RoboVac.
