the h22 came with different size injectors on different years. make sure you got a spoon ecu for the right injectors. and for gods sake, you know that its not the engine causing it to be slower. you have to know what you are doing, or be willing to put up the crap long enough to learn. btw, injector cleaner is a waste of time. unless you have always ran crappy no name brand gas, its not going to help you. try telling us what you have. what your h22? why don't you have a stock h22 ecu? are you getting any fault codes? i'll try to help you, but don't give up on it. besides the f22 is so fuckn slow!
