Here's my verdict.
Having used a full bottle of Redex in a full tank, and now having used that full tank, I can honestly say that I've noticed exactly zilch difference.
In the past I've used STP Injector Cleaner (on a previous car) and that did make a very noticeable difference, but that was on a car whose engine was on its way out and the STP probably just bought it a bit of time.
So my verdict is this:
STP Injector Cleaner 1, Redex Nil.
