We have a 07 expy el eb. does any one have any ideas for mods that would make it better. right now it is stock. I have added a resistor to the iat and it seems to have helped with the mpg's so far. i know i added on to my f-150 and its getting about 23 on the highway. any ideas would be great. thanks. I will post pics as soon i as can. we already had a hit and run on it and only have had it for a month.
