Blow-thru or Draw-thru?

On Pro-M's recalibration sheet, they ask about blow-thru or draw-thru, I'm assuming this is the MAF? What do I need to put?

Draw through is like the factory setup where the engine (or power adder) sucks air through the MAF. In a blow through, the maf is between the blower and T/B so its Blowing through it rather then sucking. I would assume you have the drawthrough as you dont have a poweradder

Awesome, I figured it was a draw-thru, just checking though. Thanks!

not to steal your post but how can you tell the difference between the two? Can you tell by looking?
