[QUOTE="Nobody Special, post: 979924, member: 9932"] Since you seem to know me...... I agree completely on the too-high pulse width statement from "tuners". I see it very often. However, my point being that if a person were to do a test with four 160-ish CC injectors of equal capacity - one with a stock nozzle and the others with a 30%, 100%, and even 400% - run at, say, 5.0mS ACTUAL at 3000 RPM ( 5.0mS isn't possible in a truck at that RPM, but on a flow bench have at it), and 3000 PSI, they would ALL fill your graduated cylinders the same amount after 1000 shots....... Your test proves nothing other than the capacity of the injector is the same between the two. I like Nate's idea. You will never, EVER see me tell somebody that 400/400 injectors will work well for ANYTHING. I QUIT tuning the 7.3L commercially/remotely because of unscrupulous businesses that would convince people that anything with a nozzle size of larger than 100% is completely streetable on the first iteration of tuning attempts....it just ain't happening - especially when remotely writing calibrations. I won't touch them because 90% of the people who read forums and see that someone is running 400% nozzles somewhat successfully will never be happy on their daily commute with kids in the back seat and groceries under the topper.
