how big is your port? and make sure you have your infrasonic filter set correct.

port is 3 inches wide all around, 25 inches in total length, it is an l port, used the torres box calculator off the site to do the math, is my port to skinny as in diameter

you mean 3x3 as in a square? if so that is your problem (possibly also your amp). You say L port, but mention diamater so I am a bit confused.

ok, so what are the dimensions of your port? 25 inches long but how big is the opening of the port?

and maybe take a picture, helps me understand better
