Professionally assembled using all new parts, Nostrum pumps are 100% tested for leaks and dynamically tested at engine relevant rpms and target pressures to assure quality & performance. This kit upgrade with Dyno Spectrum tuning is capable of an amazing 666 ft-lbs of torque at just 3500rpm!!!! (as demonstrated on NHP's stock RS7 development vehicle). Even with stock injectors, the vehicle is able to run out of mechanical fuel pump at low RPM. This kit upgrade with Dyno Spectrum tuning is capable of an amazing 666 ft-lbs of torque at just 3500rpm, while the higher operating pressure allows for more fuel delivery, increasing horsepower up top. This is basically a free injector upgrade, without having to go through a 22 hour injector install!
