| Dude... save yourself the headache, and cough up the cake for a set of nismos. DW, in my experience, are junk. Now I know someone is gonna wanna come on here and have a pissing contest and tell me how their car runs buttery smooth, and would smoke mine with their DW injectors, but I chased an issue with my motor running right for almost a year until Greg at SpecialtyZ asked me one day: " what kind of injectors are you running" I say: "DW" He says: "There's your problem, change those, your car will run fine." Sure enough, a new set of Nismo 740's and she IMMEDIATELY purred like a kitten. He said they had about 10% of the "by mail" tunes they did on chips for cars with DW injectors that actually worked. He said even in the shop on the dyno often it was often difficult to get a motor to run right. Upon inspection, the drilling of the plates on the DW injectors was crappy. And when they take a 270 or 370 injector and try to make it flow more, it will, that is at wot, but in between they are all over the place. When each cylinder is running at a different A/F ratio because the injectors may not match at any given load condition, your car will run like shit. Just my opinion, based on spending 2k on parts trying to fix it. I never even considered injectors because they were new. Ditch that junk and get some new ones, you will thank yourself, and your Z will thank you...
