Make your Duramax Fly. With the Allison 5 and 6 speed, the Duramax is
already fun to drive. Why not add an addition kick with DDP Injectors.
Unlike an electronic box, honed performance injectors are almost
impossible for a factory technician to detect. With DDP's Balance Honed
injectors you can be confident that your warranty will not be
compromised and you'll have the extra pulling power to beat your friends
up the mountain.
These 75 horsepower
nozzles will give you about 75hp at the wheels. You can use these in
conjunction with an aftermarket electronic box or downloader without
the worry of draining the fuel rail dry with most programs. We highly
recommend the use of a dual injection pump setup.
Mileage will increase about 1-2 miles per gallon once the initial fun wears off and you start driving normally again.
