i checked my compression on my stock z6 and the normal bolt on mods but my compression was 12, 12, 12, and 13 through each cylinder
 
well lots of things, i would check the timing first. but that being off or bad valves,rings,hole in the pistons,cracked head,bad head gasket, ect
 
Given the location; I'm assuming the unit of measure is bar. If so, that's about right and you're just fine.
12bar=~174psi
13bar=~189psi

Sounds right; about a 9% difference which is well within spec of what's suggested(which is about 15-20psi difference, or about 1bar)..

How accurate is the tool you're using though? As I'd honestly doubt you could be on 12 or 13 spot on.
