Pinky you seem to have a good general knowledge on turbo applications. Does lets say at 6 lbs does pump make more power than c-16? It sure feels so. Obviously I only run c-16 {damn this stuff is expensive} when I want to turn it up, but was curious. Maybe it's just me comming off 20 lbs of boost and 6-8 lbs feels a little weaker compared to6-8 lbs on pump...Also does c-16 make your bike run a little richer or leaner because of the slow burn characteristics of the fuel? Reason I ask is I have a very small hesitation around 2500 rpms that is not present on pump fuel... Anyone else chime in also if you honestly know the answers to these questions. thanks
