It's been my experience that:
- Most folks start with a simple 1/8" ~ 1/4" "bump" (past factory mark) in the static timing. It's good for mildly tweaked pump/injectors.
- The more aggressively tweaked pump with moderate injectors gets along with the pump turned to the head.
- More static timing advance requires jumping a tooth at the pump gear, combined with retarding the
IP case. To get it back centered in the adjustment slots.
- And then there's the nuts who run two teeth advanced. In my defense, with a lot of advance, one is left with little room between the
IP top and the engine's head. You can't get any wrenches between the **** to work on the
IP.
. . . The second tooth advance allows one to then pull the
IP well back away from the engine head. Now you can do **** back there.
I wonder if the OPs timing was advanced to the point it needed to be pulled back past the stock/OEM marks (retarding).
Don't forget the VE sports dynamic injection event timing based on case pressure, which is based on
IP main-shaft speed and a pressure regulator, all of which is influenced by a fixed orifice overflow-valve.
Forgive me if I'm preaching to the choir.
