I assure u it has nothing to do with the map and everything to do with your stock headers they are very restrictive
U can suck all the extra air u want but u have to be able to get rid of it too
Im running a modified version of the 20050 map secondaries open ect ect as my base tune and the pcv with custom dyno map which i assume would be leaning and richening that map up where needed . the base map isnt compatable with roadsters
but im happy to email u the pcv map. Although it wont be anygood for your machine as u have stock headers and a different exhaust system.
If you want those extra ponies i would be changing the headers and getting remapped and they will appear. The map you have would be perfect for your setup i would say its just those headers robbing u
