I've played with the bumpers and the latch, and neither has made much difference. If I raise the bumpers any higher, the hood will be hard to shut and pop. The latch is already as high up as I can move it. The adjustment I made there only helped me out about 1/16". Is it possible that the frame is out of whack. I have crawled up into the engine compartment a few times, but i doubt that would be enough to bend anything.
