They waved the restocking fee because their descriptions were not accurate. I still had to eat the shipping costs though.

If it was OTTP there would have been a ridiculous restocking fee on top of paying for the return shipping. Been there, not doing that again. 
So as stated in the original post, the reason I want to add a 5th injector is for additional fueling for E85 and to help keep the valves clean.
Would there be any issues with running a 5th injector on 93 pump gas just for cleaning the valves? I understand it will require additional tuning to keep it from running rich, but are there any other problems it could cause?

I don't see how it could harm anything, if the tuning on the direct injectors is adjusted for the fuel coming in from the 5th injector. Might be a little tougher to get everything perfect, since the reason for the DFI was to make the fuel mixture more 'precise'. I would also consider running water/meth for that 5th injector, rather than fuel. Same valve washing benefit and probably easier to get the mixture ratio right - at least there seems to be a little more leeway with the water/meth.
Running pump gas on the 5th injector was more like an interim step. Since the long term plan is E85, I don't want to add an additional tank/pump for water/meth. Plus having a tune ready for pump gas incase E85 isn't available would be nice, without having to mess with the 5th injector controller etc.
This is where ZZP put the 5th injector on the donor I bought.
