March 2, 2010I have an early 08 6.4 and wanna do a single stack but that requires to remove the dpf which would mean i would need a tune correct? the build date is 03-07 so i have to keep below 250hp. i wanna do the spartan tune but what should i order, should i get the dpf delete pipe and cut it back for the stack? i also live in NJ where we have the worst laws so i would like the least amount of smoke as possible. thanks erik
March 2, 2010The 275 and 310 tune smoke the most. You will be ok with the 250 tune especially the towing one. And you will need a tune for it to run right w/o the dpf. Whether it is h&s, sct, spartan. The spartan tune is probably the best because of the constant updates. Plus you can get a tcm tune for early make 08`s like yours. Also hang onto the dpf so you can install it when it is inspection time. Join powerstroke.org for more info on 6.4`s. This site doesn`t have much.
March 2, 2010Ok i was just outside looking at the exhaust, it looks like i can keep the dpf and remove the muffler and 90 strait up from the end of the dpf, then i dont need a tune correct? I still wanna do the tune but if i can keep the dpf i have a better chance of not getting a fine. how do you think that would sound with the single stack and a dpf?
