6.4: To tune or not to tune???

[sugelle]

Guys.....I am new to this site and to diesels. I just bought a 2010 F350 with 6.4 .....truck has 11,000 miles on it. I have been doing alot of research and I see alot of 6.4 owners are doing the DPF delete. I priced out the recommended H&S MiniMaxx and was going to buy one but started getting cold feet. I am always nervous about modifying my truck and having issues or dealer void my warranty. Also....I'm not really looking for more HP, if I bought one it would really just be to delete the harmful DPF regen's. Truck is my daily driver and I dont want to put too much HP in it and create issues since it is stock.

Here are my questions for those that have done the delete and run a minimaxx tuner:

Will my exhaust be loud once I remove the DPF?
will it make the truck smoke noticable?
For the delete pipe....do I need one with the bungs and reinstall all the sensors from DPF pipe?
What is a "safe" tune to run that will increase MPG and not put too much HP on the drivetrain/motor to cause issues?

exhaust will be alot louder but the 6.4's are not nearly as loud as a 7.3 or 6.0. they sound like a jet! it will only smoke on the higher hp tunes such as a 310 or 350. will smoke some on the other race tunes like 275 but only if you lay into it (someone else may be able to give more detail on this as i dont run these tunes). if you run h and s it does not need the bungs and i would think a safe tune would be somewhere around 210-275 (havent heard many isses with them) if your looking just to remove dpf and egr you could run a low hp tune like 40hp or even a stock tune with dpf removed. but remember the higher hp tunes usually yield better mpg's. you COULD safetly run a 300hp tune if you easy on it and dont try and show off.

Another question....what is pyrometer and do I need to buy the extra sensor for this?

If you want to increase the reliability of the truck then tune and delete. You can run the lowest tune that's fine. If using the mini maxx you just use a delete pipe and zip tie off the harness for the sensors. If you want a stock truck then get a 6.7, it's superior to the 6.4 if keeping stock. But if your going to tune and delete, 6.4 all day.

If nothing else, if you're worried about warranty, buy the tuner, exhaust and EGR delete so you have it on hand before you can't get them anymore then tune and delete after warranty is out.

Clearly he said he just bought a 2010. Not so sure this advise is what he's looking for!

Inside the cab it will be quiet. Outside it will sound like a jet as previously said.

Yes, there will be times when you see smoke. Mostly in situations where the boost is building quickly, therefore more fuel is being added than the engine can burn at that time ---> smoke.

If you get the Mini Maxx, you do not need any sensors. In whatever exhaust parts that are being replaced, you just leave the sensors in and disconnect them from the harnesses.

You can run the Mild tune and vary your power from there. On the HD300 tune, you will build boost very quickly. The Easy tune I don't run.

U can get exhaust with a muffler. My 5" flopro had one. Not loud in the cab, it won't bother u. TUNE! For sure....
Check here for a good offroad mini maxx. I saw one here the other day. The new tunes don't smoke with the mini unless u hammer hammer on it. Those two things are easy to swap if u needed warranty work. Cant comment on the others tuners

Yep.

And, no pyrometer needed.
