I have my truck for sale and as soon as its gone im looking into getting a 6.4. What is the best tuner for them i heard they dont get to great of mileage so im looking for that and of course lots of power

 

Spartan is badazz on the 6.4

H&S is what U run. Love it!

 

Does H&S make a 350hp Tune

 

Think if I had a 6.4 I would be looking at H&S or innovative

 

You really can't go wrong with Spartan, Innovative or H&S

Spartan has been having serious shifting issues, I don't think too many people even use them anymore. I'm not sure if they have resolved that issue yet or not. Innovative would 100% be getting my money no questions.

Mike @ Kem is also highly rated, using the H&S stuff.

 

Honestly, you cant go wrong with Spartin or H&S They were my 2 choices when I was deciding on what I wanted to run. What I did like about the Minimax was the price was cheaper. Spartin does have more tunes to decide from on theirs. Its really up to what you like better. Theirs tons and tons of forums on this subject on powerstroke.org or what I did when deciding was to do a live chat on performance truck products. Explain to them what you like and dont like, and they can hook ya up

 

I have an SCT Livewire that I love because it can correct for diffrent tire size (pretty close to accurate), turn off the CEL when the DPF and EGR go MIA, record data, clear CEL/DTC, adjust WOT shift points (on the canned tunes-not sure on the custom stuff). SCT won't be making anymore so once stuff is gone the only way to get one will be used. (Thank you EPA and a-holes who blow smoke all the time) As far as who to run for tunes that's personal opinion, Spartan shifts harder but has good stuff, KEM and Innovative seem to be better for DD stuff though (again my opinion). Check out PowerstrokeArmy.com-lots of good info on stuff if you do some searching.

 

I still have 1 year 10 months left on my warranty, but I'll be getting a tuner & DPF/deletes
