So what has been found out?
They all, as HRT stated, put out great work. If you are looking for the best price and staying within the typical 250/100 or under sizes Rosewood is hard to beat. When you go larger you are going to get awesome performance from Nate@Unlimited, Cass @FullForce, or Dave@Swamps. Take some time out of your day and give each a call and do some Q-n-Aand pick who makes you warm and fuzzy. I personally went with Nate and could not be happier. Every one listed has customers with low and high hp rigs that feel likewise. In this case it really is kinda hard to make a bad choice in picking a builder out of those choices.
To address the flow chart comparisons from the small amount of knowledge I have picked up over the last couple years there are extra mods that can be done to injectors to reduce internal restrictions and increase flow and speed. That work with some injectors is at an extra cost. Without knowing exactly what work was done to each set of injectors you can not be sure its an apples to aples. Volume of an injector does not effect actual flow rates. 250cc-300cc-750cc vol capacity can all have the same flow rate. Now if you asked each builder to put out a injector with specificl specs and to pull out all the stops you could then have a head to head.
