I was orignally gonna get a set of DDP stage 2's myself, but waiting to get a tranny upgrade. From what i read about them, they seem like pretty good injectors, and i seen that they raise fuel mileage about an extra 3 mpg over stock!

Of course, no way is that exaggerated.

im running sdx 5x.014's and love them. my turbo is a stock hx35 with the small exhaust housing on it, and once i start to build boost, it clears up.
Yeah Right....5x.014's+HX35/12+Clears Up=Me putting the BS flag up.
You do not have enough air to clean up a set of 5x.014's UNLESS your small 175hp pump is all stock.

After what I seen with a set of DDP 4 that I had bought new I will NEVER put a set of them in my truck.Pay outrageous amounts for a injector that they claim is the correct spray pattern only to find out when they are checked they are not and then also find 3 of your new out of the box injectors all pop at different presusures and pizz fuel all the time.Stick to the SDX injectors you will,be way better off and get a product built by people who care about their work quality and the reputation........Andy

Just got a set of 125hp DDP injectors last week, and all I can say is I am impressed. Don't know what brand my old ones were but they were supposed to be about 75-80hp, and these new 125's don't smoke as much as the old smaller ones. Since I didn't drive the truck for about 2 months, because I knew the old ones were bad and didn't want to destroy the engine, not knowing exactly what was wrong with them, I can't be totally sure about the power, but they do feel like they got more stuff to em. I think they are just that clean, so far I am happy with them, but only put about 400-500 miles on them so far. Hope this helps.

Thanks for everyone's input. It seemed like DDP or SDX were both good choices. I was about to pull the trigger on 75hp DDPs, but then decided that I might spray it a little, so I went with the 90hp SDXs.
