Default KA mysterious misfiring...

Hey guys! Im new to the forum so bear with me as I get used to the formatting. I own a '96 extended hardbody with the KA24E. I have big plans in the near future of installing a turbo and making the ultimate daily drifter. before such goals are achieved, I am slowly preparing the truck for the boost it will soon receive.

I bought the truck 4 years ago and have always had a slight misfire that's been plaguing my life. Ive replaced the fuel filter, distributer, did a timing chain and guides, spark plugs (iridiums) and wires, as well as the coolant temp sensor. Not to mention the copious amounts of fuel additives to try and clean my fuel system. I am stumped.

The miss is very subtle. So much so as that it doesn't throw any codes or give me a check engine light at all! It gets worse as I give it throttle or let off till about 3k rpms. Any help out there is much appreciated! I will try and answer as many questions as possible to help you guys further understand my dilemma...
