I would put a delete kit on just as soon as i broke it in good the low sulfer diesel and emissions crap is wat messed the ford motors up in the first place
I would BUT the only reason i'm buying new is for the 100k bumper to bumper warranty, I already inquired about tuners/chips/deletes etc and I was told no flat out.......doesn't bother me much, my dodge was fully deleted, tuned etc etc and while it was stupid fast it wasn't anything spectacular OR anything that I NEED to have now......back then I was single with no one dependin on me other than me, now I've got a little one and a GF to support.......growin up sucks but if I could I still wouldn't change a thing. its all about priorities and a fasto truck ain't one of em nowdays
