Only 7.4:1 compression?

After ccing my heads and piston, I found I only have 7.4:1 compression on my 3.4 930 (with 98mm Mahle pistons). I'm adding EFI and twin plug and now I'm thinking I should have gotten new higher compression pistons. I'm planning to have over 500hp with possibly more in the future. My question is: should I go for more compression for low end power or stick with what I have for more top end power and cooler track running?
