As far as I can tell it's bone stock so naturally I want to change some things. First off a tuner. The bottom line is I'm not paying $1200+ for a tuner so what are my other options? I got an extended warranty through Ford so the DPF and EGR stays for now. Most of what I'll be doing is towing and the occasional trip to get muddy that's it. Im just looking for a little extra power so what do you recommend? I know everyone knocks canned tunes but I'm only looking for like 40hp.
Second is exhaust. Without a DPF delete is exhaust even going to make a difference?
Third is Intake. I was going to go with a simple drop in filter. From what I've read on here that should be fine for what I'm wanting to do with the truck.
In the next two weeks I plan to flush the coolant, change my fuel filters and change the oil. Dealer said they did it but I always feel better knowing I did it instead. Also it will be getting some interior upgrades also. I read the F250 is the most stolen vehicle in the US so an alarm is a must. It needs some window tint on the front bad so that will be getting done this weekend. My wifes dad is a rep for Kenwood so he's getting me the DDX790 7" display head unit for practically nothing. I have two boys so an overhead dvd player is on the list. I also have a JL Audio 600/1 amp and a 13TW5 woofer I want to get put in. After researching here I came across a fella that makes custom boxes for that size speaker that goes behind the seat so I'll be ordering one of those soon. That's about it for now. Should be a pretty nice truck when I get done with it lol!
Great forum and thanks for any help.
Good looking truck! as far as your mod questions I suggest looking at the General 6.4 Modifications sticky.
1. I personally will never own a 6.4 with a DPF or EGR intact. It just kills the motor over time. The longer they stay on the more your engine hates life (not saying there aren't people with high miles all stock, just saying there are fewer of them and there is a much much higher chance of expensive repair bills with those paper weights still on). That being said, I wouldn't add a tuner (or spend the money on a DPF-on tuner). Save your money now for when you want to do a DPF-off tuner.
2. A DPF back exhaust yields no benefit. Just looks. Won't sound different, won't perform different. The DPF is a huge restriction. Think about if you hook 2 straws together and try to blow out thru them. Now change the second straw for a larger dia straw, you are still blowing thru a restriction, so nothing changes.
3. As far as the intake, don't worry about changing it in stock form. You won't gain anything. The stock filter actually flows pretty well and filters well. Until you start adding power (i.e. add more than about 200 HP, you can run a stock intake).
And as always with all 6.4s... maintenance, maintenance, maintenance....
