my hood appears to be a little loose fitting on the drivers side, of course everything is tight, but if you pull up on the right corner in the front its nice and snug, the left side is not nearly as snug, this causes the hood to vibrate a little on the left side when driving on the freeway. the hood is ever so slightly above the left fender just slightly when its closed. I loosened the front latch and moved it all the way down to try and pull the hood down a bit more, anyone else had this issue

It sounds like the common hood shake issue. But it also sounds like you have a fitment issue, too. The fix to the hood shake is to adjust the bumper about 1/8 - 1/4 turn at a time to stop the shake except it sounds like your hood is already above the finish line of the fender. My hood shake is mostly resolved but will still occur on occasion at about 120 MPH and depending on wind direction and speed.
