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.
As always, this product is covered by our 1 year warranty. Please see our Policies section to read more.
