is this true for the turbo motors also?


Probably so, usually you want to be at or a little above the peak torque RPM for the engine. On a 22RE, that is around 2800:

Not sure on the 22RET what RPM that is.

Also makes highway driving nicer, since if you are a little above the peak torque RPM and hit an uphill grade, as your RPM starts to drop a little, the torque is holding even or even rising a little. If you are driving right at 2800 or below, you hit a slight upgrade, engine starts to slow, torque falls off and you need to down shift sooner and more often.
