This. My cutoff for shifting to 4th is generally 45.

That and you'll seriously piss off your turbo.
I don't accelerate below 2k in ANY gear other than 1st/2nd. I'm not a huge fan of overboost. No, I'm not talking about just plain "boost" that car companies are now trying to relabel as "overboost" because the average driver thinks it sounds cool.
