I have an Edge EZ and RV 275's. If I was to do it again I would go to the Mach injectors. Don't get me wrong I like the RV 275's and smoke it NOT even close to being bad but I have a friend with the same set up but has Mach 1.5's and there a much better injector! MORE POWER and a little more smoke.
Good Luck!
