The only thing i can think of in that regard is moving the IP while the engine is running. Very hard too do with the steel supply lines hooked up but I've heard its possable.
Advancing the pump (pushing it toward the block) on an engine with lots of miles could help preformance. Better to replace the timing chain tho
