"Lots of manual transmission cars made after 2010 have rev hang" I think this is similar to "skip shift". The idea is to force you to shift from 1st to 4th so you use the more efficient ratio. Stupid idea in my experience since it forced higher RPMs in an inefficient gear and can have some drivability issues in traffic and on hills. You technically don't need a tune to eliminate this. They make jumpers that sit between your computer cable and the transmission that eliminate the gear lockouts. You could also pullout in second and it would bypass the skipshift logic since you aren't in first.
