Iv'e done the test already. My friend has a n54 with jb4 + intake vs my car which is xdrive +n55 + procede v5 + downpipes. On a 2nd gear pull it's fairly equal but once we get in 3rd gear he has about half a car in front. Bare in mind he doesn't have downpipes. N54 pulls harder than n55 period!!!
I'm curious to see the results if I get the jb4 for n55 and do another comparision with my friend.
