So my 2005 ford f250 has ak&N intake and a diablo sport tuner, currently set on the economy tune. Anyways my question is if i am not beating on my truck.. i drive it like a friggin 80 year old grandma (the slow and sane ones) d i really need to upgrade to a 4inch turbo back? or are my EGT going to be ok ?
