so I've been finally finishing fixing the last issues on my car (ac, and a couple suspension stuff) I've been looking at getting more mods on my motor. I've found I've wanted to start running e85 and get some higher flow rate injectors next. From what I've found the ls4 uses ev6 style plugs and seems to work with the injectors the ls3, ls7, and l99 pretty well from a grand prix forum. I've heard some good things about the 42# injectors those motors use, But is right for me to assume that if I wanted 60# injectors instead, that as long as they're supposed to fit those motors, it'll work on the ls4? If so, would going 60# be too excessive or should i just go with 42#? Either way I'm having professionals tune my motor after installing as I'm just a diesel mechanic not a tuner. Any thoughts and ideas would be helpful.
