I have a 05 screw with the 5.4. I was looking at putting SIDO exhaust and the gotts mod. Some have said this will make the truck lean. I contacted Troyer and they said that it is possible on this motor. My question is if i put a Edge CTS with canned tunes will this help out or can I tweak it or do I have to get custom tunes.
