You can change an order until it has been pulled (until a VIN has been assigned). If you're going to be doing a lot of highway miles then you may want to keep the 3.31. If you're going to be doing a lot of stop/go or runs down the track then try and get the 3.73. The 3.55 is a nice in-between. All just IMO other than the order change info.
