I’ve heard of lots of issues with a sticking butterfly valve and idle problems, along with no tangible benefit from any non-OEM TB. I suppose there’s probably no harm keeping the BBK TB on until you have a problem.
And, yes, you can do the gears now and just update the tune later for new gears. But I think going from 2.73 to 3.73 gears would really be something you’d feel. It was a big deal for me just going from 3.31 to 3.73 gears.
