Tracy and I have been discussing this injector flow rate anomaly for years -  
 
For some reason, I was certain that the Mazda injectors flowed more than they were rated for, but after sifting through some old logs, that's not true for all Mazda injectors.   I sent 4 slightly used 550's to RC Engineering, and they tested them at 547, 549, 551, and 551.  If that ain't 550, I don't know what is :-)  
 
I guess I'm baffled now.  Does Mazda operate them at 5 volts or something, rather than 12V?  That would slow down the response time.   
 
 
Hey the HKS is a good little engine in my opinion - not as good as a light weight rotary (which we don't have yet - Richard! get a move on {:>)), but it'll get you  flying again. 
 
Thanks for the comments.  It can't hurt much to try it, because I've already got people who want to buy it if it doesn't work out.  Still, it's as much trouble to install as the rotary, so it really comes down to a weight issue, and perhaps whether I'll ever get my redrive from Autoflight...
