I think one of the biggest differences in our cars is the tune. He has a custom tune on his N54 and I have JB4 stage 2 ISO on my N55.
He also has no sunroof and has a upgraded intercooler. I think that's why I was so surprised with the outcome. There is another 1er N54 here that just has a down pipe, catback and JB4 stage 3. He beats the guy with FBO and the custom tune by about the same as I did...
