A few mods that I couldn't "feel" a difference

Try at least 3.73's before the aluminum driveshaft, & you'll be able to feel it. Mine cured a top-end shake that scared the hell out of me the first time I took the car to the track with the new gears. I won't consider gears now without a driveshaft factored into the cost.

You have to consider a lot of those mods make most of the extra power at the very top of the RPM range not across the entire RPM range. So unless you are taking your car all the way into the peak HP to see those extra 5 or 10 ponies your right you will never "feel" them. I felt a noticable gain with nearly all of my HP bolt ons. But that's because everytime I do something new I take to the street by my house and ring its neck a few times. I take it all the way to the top of first and second and normally only feel the difference right before it shifts. I know with my CAI intake and pullies this was the case. While the ported manifold and MAF (did them at the same time) made a more dramatic impact across the entire RPM range.

I definitely felt both a silencer removal+K&N filter and ASP underdrives.

you'll feel a new upper/lower intake, guaranteed. then maybe the t/b will have a reason tl flow more.

Thats the thing, mods on there own will often not feel as though they did much, but pair them up with other supporting mods and the whole thing comes together. Such as just putting on a catback will seem ok but if you do the mid pipe and headers at the sametime then the whole thing works together and you feel alot more of a power increase.
