Emissions, EGR/DPF Delete, Tuners, & Catastrophic Failure...

So Let me get right down to it. I Recently Bought a 2008 F-250 from the dealer used with 70k miles on it and everything's good. I've been doing alot of research on the 6.4, I've owned many 6.0's but this is my first 6.4 I do love the power this thing puts down stock, but im not one to leave things "Stock"... As far as deleting the egr and dpf, Which I know to be important not only for gas mileage and For making power, BUT also for engine longevity... Even if you didnt want to remove the dpf for the gas mileage ect, but from what I understand the dpf and Regen-Cycle are the main reason why these 6.4's die...

If you havent seen this video and own a 6.4 I HIGHLY recommend taking the 10 minutes right now to watch this. I've learned more about the 6.4's mechanics from watching this guys videos than anything else.


and the Main REASON I CREATED THIS THREAD;

What tuners can you buy new, Right now that Support DPF and EGR deletes, etc. and are also decent for tuning. I hear that now some companies cant sell tuners that have the deletes because of the EPA and other new regulations.
I know you can upload custom tunes on the sct, so I imagine a tuner could write the delete into the file, But im not sure...??? but also I realize that sct isn't the preferred tuner on the 6.4 like it was in the 6.0's. Do the H&S or the Spartan tuners support Deleting?? (that I can Buy new)!

Lastly EGR Kits, Does anyone see and legitimate benefit to using a block style plate vs using a complete delete kit? Any experience, Advice etc would be awesome.

My goal was to make one UPdated Thread to keep some info for the tuner & Delete Situation. I seem to find alot of useful info only to realize its 2 years old!!!

Don't let those videos scare you, if you listen close most of those engine problems he talks about come out of 450 service trucks that idle all the time with egr/dpf intact.

Also, SCT offroad tuners are great for 6.4's if you get custom tunes from gearhead or IDP. H&S and Spartan are good but more expensive. Rudy's diesel does sell the SCT's with deletes in the files. I found my SCT on craigslist and bought gearheads street file. Truck runs awesome, one drawback is I don't have gauges like H&S and Spartan do. I also prefer the complete egr delete vs the block off plates as the coolers *could* still cause issues because coolant still flows thru them if you just block the exhaust. I did the bare minimum on my truck and I think I paid about $1200 for tuner, tune, dpf delete pipe, egr delete and couple jugs of coolant.

You're taking a gamble buying any used diesel truck, just keep up on your maint and enjoy the 6.4.

Did you do the egr delete yourself? To me it seems like you could just install the block off plates between the egr cooler and where it meets the motor? It seems like leaving the cooler there would be the easiest way? I mean sandwiching the plates where the cooler connects. Also How long did it take?

I'm pretty handy and assume I could do all the deletes in a day, Does this sound about right?

Yes, I did mine myself. Took about 4 evenings after work to complete the job, its not that hard just time consuming. The plates are easy to install, but they don't stop the coolant and *if* one or both plugged it could hydro lock the engine. I just prefer the cleaner look of all that crap gone. You could everything in one day easy, I just didn't have the time because I started during the week and had to work on it after I got home from work.

Also don't buy the expensive delete kits because of the name, they are all basically the same and some vary in price up to $75 or more for the same components. You can google instructions if the kit you buy has vauge ones.

Sam Hain, has given you very good information. I also agree with him regarding your EGR....Delete it all, you won't regret it.

I live in California, one of the reasons I would leave it in would be to pass visual inspection if it ever came to that. is it possible to do a complete delete with the egr still in place? I imagine the complete delete just uses a hose to bypass where the egr would normally connect, right?

I'm planning on deleting the DPF right away too so leaving the egr in place for visual might be pointless... I dont see someone not realizing the dpf is gone, but catching the egr delete...

I actually have a guy that just signs my trucks of on smog for 2 bills, but i mean in case he dies or something I dont want to have to reinstall the whole egr, but rather just hook it back up

Full delete actually uses block plugs to go in place where coolant flowed between coolers. 1 up front & other under thermostat area. Then either valve is replaced w/elbow or blocked & keep valve in place, then Egr crossover (hortz cooler connection) tube is capped.

If the egr is disconnected (Blocked off) then how can it hydrolock the engine? if coolent actually made it's way into the egr wouldnt it be blocked off anyway???

Im not arguing im just playing devils advocate because I dont know and am information hungry

The block off plates only stop the exhaust the coolant still flows thru the coolers. Stock 6.4's are known to have sand/grit in the coolant from where the block was cast. Over time that junk could build up and cause them to stop up and cause coolant to back up.
