So I got some RX7 460cc injectors off of eBay. I sent them off to WitchHunter Performance for cleaning and flow testing. They turned them around in 2 days! The crazy part is they called when they were done saying that NONE of them worked when they got them. I guess they had been sitting for awhile. They mark each injector, and replace all O-Rings, caps, etc. If you're looking to get your injectors serviced, go here. This is the best $60 I have ever spent.

Here's the printout they sent.
