N55 Dorch Engineering HPFP Lift Kit (on a core exchange basis) EWG Wastegate flow spec 38% (* note details below)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. 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!

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. 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.

Had to look hard to find it again
My husband loves this watch. This is his second one, and it was hard to find this one, exactly like the last one - which lasted for years. Good overall watch, easy to read, reliable.

POOR PACKAGING
Disappointed that the watch arrived only in plastic bag without bubble wrap envelope. The plastic box was broken and the paper box old , I bought it for my father as a gift, and I had to buy other box because it seemed like used. Good: it arrived on time. The watch is really nice and functions well. BE CAREFUL WITH PACKAGING!!!

Don't buy its a waste.
Very cheap watch. Sharp edges and adjustment of the band although easy to do, the parts are very flimsy. Don't wase your money.
