Actually I don't understand how this would help at WOT. It's just a small air passage. Yes?
At idle, consuming 4 to 6 cfm, or maybe 8-10 with a high idle rpm, the compensator will flow a small but noticible percentage of that.
At mid to high rpm, WOT, its going to be a tiny fraction of a percent.
(It's not like a bleed into the circuit which alters the pressure difference and the density.)

Here's some of Mike's tips on removing those tubes without damage.

That might be easier than drilling from the bottom unless you have a cross vise on a milling machine or drill press and can index the well accurately???
