The stock ITR injectors are supposedly 235cc injectors/ 240cc, what ever, either way, assuming you're running stock ecu and everything else, you should be able to run upto a 310cc injector without any serious problem, although keeping in mind that your computer stock can only correct up to somthing like 40%. Either way, you may want to look on the actual injector, most RC injectors actually say what size they are on them, or at least the 310cc that I used to have had 310 etched on em'. You also may want to check your fuel pressure, it's entirely possible that it's very high, assuming you have a fuel pressure regulator. Your non-static fuel pressure should be about 42psi stock. you also may want to check the impedence of your injectors, they may have removed the resistor box by accident or something, or your injectors might just be dirty. There are a number of different things it could be. If you want, and I'm assuming for the most part you are stock???? I still have my stockies with the injector clips, if you want, you could borrow them to test out the theory, and find out what the problem is.....Let me know.
