Final drive do affect rpms a bit, but not as much in the broad spectrum of things. The purpose is to keep the engine in the correct powerband a bit longer. If you're simply crusing, it shouldn't really matter. If attempting drive with more "spirit", then you would need to shift a bit faster to get the full affect. 4.5 is not bad at all really, its a matter of you getting adjusted to it. If you weren't sure why they are used, why did you purchase one?

Changing the final drive can help you accelerate quicker (less top speed), but your rpm drop will stay the same.
You could always swap in a 4.7 ITR final drive or raise your shift points so you fall in your "sweet spot".
If your still dropping too low after that,its time to open the tranny and do some gear swapping.
Or just get a whole ITR tranny!
