I have a 2009 F350 crew cab dually auto trans lariat, it currently has 18,000 miles on it. I have purchased a 5" turbo back exhaust with no bungs, H&S mini maxx, and AFE stage 2 intake. I am getting ready to install this setup. Is there any thing i should know/ look out for while installing this?? Should i do a egr delete right now?? Is it a big plus to delete the egr since i am doing all this already? Thanks for any input.
