Re: fuel rail?
Like Unit says, higher horsepower applications really benefit from the increased fuel flow. However, even moderate HP applications can see an improvement with reduced starvation at the injectors, particularly because of the 6-5 pulse. On the engine dyno, we've seen lower EGT's on #5 with an aftermarket rail because it isn't so affected by #6 firing right in front of it.
