DIY Intake, Less Whine?

Hello All. I'm a newbie, and I am just getting around to modifying the 2001 Lariat I bought last August. Today, with detailed guidance from a post by Maintain (thanks) I put in the NAPA DIY intake. Simple mod. I also pulled the wastegate tube. Now, I swear it seems that I get less turbo whine. Power seems fine, but the engine definitely sounds a bit different, perhaps louder.

Any clue on why I would hear less turbo?

Your welcome...

I definitely noticed an increase in turbo noise after in the install but then again I think I did the foil delete mod at the same time as well.

has anyone cut away any of the hood insulation around the DIY napa filter? To allow better flow?

I haven't but I know what you mean. My hood contacts my filter. I used a Baldwin PA2818. I think I remember reading where it is slightly larger than the NAPA and some of the other similar filters. I plan to research and look for a slightly smaller filter, if available, next time.

As far as tubo whine, I don't hear more either. I hear the blowing/sucking that the big filter does. It sounds real cool when climbing through the mountains like I did yesterday. (I did the wastegate delete too but really can't tell any difference. No gauges though.
