Maxed pump timing

[Fast12v]

Just got my hands on a maxed out 215 pump flowing 600cc. Curious what kind of timing I should try with this new pump. I was at 21° with my old pump and I liked the way it drove. It’s a daily driver/weekend fun truck so I still need it to be some what drivable around town. I know there is no right anwser or exact timing that I should use but I’d like to know what kind of timing others have ran with big pumps like this and how they drive. Thanks

20 works fine on mine as a happy medium. Still spools the charger and not too hot up top.
