Default Power losses due to timing

I have a 99 Cobra with a Zex wet shot runnin a 75 shot now. I am thinking of retarding my timing 4 degrees to run a 125 shot. Does anybody know what kind of power losses I would get without spraying?

10-15rwhp. You only need to retard 2 degrees from base spark for a 125 shot.

The instructions that came with the kit have 4 deg for 125 shot and 2 deg for 100 shot. But thanks thats what I was wondering about.
