Faster start up.

[superwagon]

I'm looking for a little direction on how to get a faster start up while cranking. I thought maybe advance cranking timing but maybe it's more related to rail pressure? I've datalog start up and see stock is about 2* main timing but the actual start up seems like possibly closer related to rail pressure? I really like how quickly the truck fires with Robert Ivey tunes. Anybody willing to share info or point me in the right direction?

Thanks!
