BEST 6.4 Tuner?

[Baller1771]

I was wondering which tuner was the best for the 6.4? I have an SCT for my 6.0 and want to know if they are great for the 6.4 also. THANKS

My vote is for Spartan. My 2nd choice would be SCT.
p.s. The secret is in the dpf delete.

That's the first question, DPF on or DPF off? Then we can give you our picks.

what is the difference? this is for a friends truck. as you can see i own a 6.0

Kinda a waste to leave the dpf/cat on, if your looking for power and mpg gains. Seems like the programmer/tuners that add power with the dpf still on the truck don't help mpg, sometimes mpg goes down. The dpf is the diesel particulate filter that cleans to exhaust, this is done by firing a BUNCH of extra fuel to get the exhaust/dpf very hot and burn off the soot. Some don't want to take a chance taking off the dpf(off road use only). DPF off Spartan or SCT. DPF on Superchips Flashpaq.

powerstroker67 have you seen any problems on install with the DPF delete from SCT?

Tuning your truck will potentially void your warranty...So you are going tune, you mind as well go all the way and do the dpf delete so maximum results will be seen. If you leave the dpf on you are likely to plug the dpf faster and they aren't cheap if it's not warranty work. JMHO

Very well said. We sell both brands and have seen great results from both. The Spartan is very easy, and is more capable, but you will be happy with both. The Spartans don't stay in stock very long, so if that is the route you choose, get on the list ASAP!
