Flutter noise in between cylinders During Buzz Test

How ya'll doin? Merry Christmas! So I went and got a buzz test today from a guy on here. Thanks Ken! My injectors seem to be fine. But there was a flutter like Ford example. Initial loud Buzz, Good! 1,2,3,4,5,6,7,8 Good. I don't remember which injectors but lets say for example between number 1 and 2 there was a flutter noise coming from the passenger side and again between 5 and six it fluttered again. So the injector would go BZZZZZ and then a thub thib from the passenger side and the next injector would go bzzz then the next bzzzz next injector bzzzz next injector bzzz without the thub thub thub. It did not sound like it was coming from the injectors and did not happen after each injector. Actually did a second buzz test and only happened once. Weird! Has this happened to anyone? Just changed oil and K&N w/new prefilter.
2002 F250-170,000 well taken care of miles. SCT on economy, Six Gun Banks for Display Only " I hated it", 5" MBRP, FS-2500 OIl Bypass, K&N w/prefilter, Factory Tech Valve Body, Amp Research Steps.
