One other thing to remember is that the descriptions for the maps are from the N54 and are not N55 specific. With the small gains we see from DP's, there is not that much back pressure being created. If you have seen the size of the turbine housing on our turbo you will know that the DP is the least of our worries :P The turbo is creating WAY more backpressure than the DP is.
