Something tells me that any 5th injection valve (cold start valve or other) system is the least efficient way to add power via fuel increase. Being so far away in terms of distance from the combustion chamber, plus it's relatively minor fuel increase while operating is my reasoning. If you've ever seen an injector in operation, especially under full pressure, it sprays fuel in a fairly wide pattern. I'm sure a good amount of that fuel sprayed before the throttle valve would just end up coating the inside walls of the intake system. Those fumes would burn up eventually, but not immediately as desired for more pop. Wouldn't high flow injectors plus a matching FPR be the best and most direct way?
