I just had my injectors cleaned and flowed from injector rehab. (Great Customer Service BTW) I sent in "89-91 RX-7 NA 460cc - Red Top #195500-2010" They were returned showing a flow of a perfect 480 across the board. Now 2 concerns come up. First, before when i sent another set of injectors to witchhunter i had them returned with a ~1% difference. I thought most injectors has some kind of difference regardless if they are used or new. 2nd, is 480cc accurate for these injectors?

 

Mine were all within 2 cc of each other. If they're flowing 480cc, erm, I dunno, wednesday injectors? I don't see that being a bad thing.

 

I've heared of injectors flowing more than they are rated, more than once, come to think of it, the ones I read about were also RX-7 ones.
I would not worry, be happy, you got bigger Injectors free of charge.

 

this is what mine looked like....ive seen some come back higher...lots of 550s come back 560-600cc
