Let's see some pics. Some of the ram air hoods hurt the coefficient of drag a little at highway speeds. If you are running the stock hood then your new air plumbing could be affecting the air/fuel mixture or invoking some timing changes that could impact your mileage.

Mine seemed to help but I have ram air from the top side ... the hood.... I also tried sealing the top but I left the bottom of the airbox still vented. I live in Pittsburgh and with all these hills... the best I have gotten is 24.. and thats with the ram air

It is possible that the engine management system is running a bit of a richer air to fuel ratio do to the cooler air "thinks its cold" ..
Might also be the driver  i know when i first modded my air intake i was having fun with the skinny pedal.. |

IMO, if you block off the bottom air, it could drop your mileage! I would have left that open.
