I have some rookie questions. I have a NTC3 with a D5 and a RD turbo pipe.

It was recomended to me to run 30% O' Donnel fuel. What are your opinions on this choice and what advantages and disadvantages are there to using different mixes and are there additives that I want to look into using?

Is there and advantages or disadvantages to using the Turbo button over the normal button. And also what plug do you recomend I use?

Also I live in Wisconsin so temperature is going to change alot throughout the season. Is there special considerations I need to take into affect besides diferent tunning to compensate for this?

Thank You.
