Pretty new to the 6.4s. Was a proud 6.0 owner for a long while. Just don't know a whole lot about these motors but I'm constantly searching. I was wondering if anything in the fuel system needed to be upgraded for handling these high hp tunes? Just curious cause of all the **** my buddies duramax needed just for a 150 tune. Thanks!
I'm already all deleted and have an sct with innovatives tunes.
