YES if your maf served no purpose other than to restrict air coming in, then a bigger maf would make more hp, letting in more air. This is not the case. The maf meters the air. You modify it and you throw off every calculation the computer makes off of its readings. You can dump all of the air you want into a motor, if the a/f ratios are wrong, its not going to help you. Ask the supercharged guys.
