contacted summit via their website, and asked a "question" for their DUI copy in regards to shaping a custom curve depending on individual needs. They said that it's possible for a custom curve. I plan on starting a build later this summer and will call before to verify, then post up a response.

I run a DS2 dizzy with a custom advance curve. With that I use a hp, hiigh output coil. I have used both the GM 4 pin, which made my system almost the same as the DUI dizzy, and I've run it with an MSD box. The combo with the MSD box was a large step up in performance from the DUI.

I love the simplicity of the DUI/Summit dizzy, but for performance I have seen that the DS2 with an MSD box will out perform it.
