since someone else already brought it up... ST or someone who knows more than me...
If Ford runs the CP4 on the powerstroke, and can make crazy numbers and doesn't seem to have any failures......... why do all the duramaxforum guys have problems and everyone hates the CP4 in the GM camp? Are they different models? Everyone with a duramax making additional power (and even some stock guys) seem to be terrified of the cp4 failing. And all those people doing cp3 swaps and what not on them. Is that just internet fear or is it legit?
in the powerstroke world, no one ever seems to mention cp4 failure, or even lift pump. They just slap a tune on it, make stout numbers, and they seem happy as a clam?
Not to start anything, but that h&s powerstroke with turbo swap make like 660/1240 on stock everything lol. granted it was 40psi, but its still kicking. Meanwhile the duramax they tested.....
