Flow benches and dynos are just tools for comparisons... as long as they are consistant it doesnt matter what they read . You are just looking for incremental changes between modifications using the same tool .
It's alot like yards in archery... it doesnt matter if your 30 yard mark is actually 50 as long as it is consistent .
Because no one elses eyeballs will be looking thru your peep .

So if your flow bench says you have 1000 cfm @ .100 and 1200 cfm @ .200 its ok because its just a bench mark for measuring. As long as its consistant .
