edge evo, do gotts mod? removed cai

[hart]

i have an 06 xlt 5.4. ihave 24 inch wheels and had a k&n cai on it for a year. then bought an edge evo for it. tested it for a few weeks did some research and decided to take cai off. it has more gains than stock but was told that doing a gotts mod on intake works good with the edge. the cai worked well in cool outside temps but struggled in hot weather. the truck has lost its cool weather umppff when cai was on but runs smoother than in hot weather with evo tow tune and cai off. power hungry told me that theres no extra gains to be made with the edge and cai running at the same time even after custom tune with a gryphon. can someone please clear this up for me? how do i get more gains? gotts mod? i have a magna flow muffler and 3inch tail pipe.; also liked the sound of the Cai
