egr delete

[btsb032304]

hello, i have a 04 6.0 with a build date of 9-17-03. i have done the headgaskets and installed arp studs when it was done. egr and oil cooler were done at that point as well. the other mods to my truck are a sct live wire with spartan tunes(not archived actually written for me from matt) 5" mbrp, normally a k&n intake(stock on during winter), a swamps 58v ficm. i also have a 4" lift and 35's. i was thinking an egr i wanted to do an egr delete either the first coast or gogo's kit. i guess my question is what do i gain from doing this delete. i currently have no egr issues nor have i since the head gaskets and studs about 3 years ago. do i need it or is it a waste of my money. also whats better about the whole intake kit that fcdp and gogo offer versus a kit like the sysnister. thanks for any help

also the egr is currently turned off according to matt
