One big turbo compared to 2 small ones on the 6.4, and 25 psi boost vs 40+psi on the 6.4 make for lack luster performance on the 6.7
That being said I'm not going to tune my 15...for now anyway.
The 15 does handle and drive much nicer than my 08 and even my 12 F350.....just wish it had a bit more of the obnoxious instant power my 6.4 had. But that's tuned vs stock for you ; )
25 psi boost and turbo lag??? lackluster performance?? yours must be broke.

My 2016 F350 35psi next to zero lag, 0-60 7.2 seconds Stock, safe, and one bad*** truck with a full warranty. I'll take that over your 6.4 without a thought.

Ummm, Your just kidding right LOL, that's pretty funny!

Who with half a brain would void their entire warranty on a $50-$70K truck unless you have that kind of cash to throw away.
any failure whatsoever could be blamed on that kind of mod.
Trans, Engine, drive line, no going back to the dealer to cover the cost of any failure. Everything will be the fault of something you did.
buy something out of warranty and play with it, much cheaper and more money to buy things and fix all the stuff you break.

Hence the saying "you gotta pay to play"
And yes there are lots of guys who void their warranty to tune their trucks.
People tune for their own reasons...so each to their own.
If you drive them in a normal manner, you can have a more reliable truck than the stock version with all the potential problems with the emissions equipment....plus your mileage will be much better.
I never had to take my 2008 6.4 to the dealer once in the 6 yrs I owned it, with it being deleted and tuned the whole time.
I had it a week before i tuned it (i bought it used with 18k miles on it).
The mileage i got running empty stock, was what i then got pulling my 33 ft toy hauler tuned.
Sold it with 60,000 miles on it; no issues at all.
I had my stock 2012 6.7 a month before the heater in the DEF tank went and i had to get it replaced at the dealership.
My 2015 King Ranch has so far been trouble free in stock form. But if i decide to keep it a few more years I'll most likely tune it as it just seems so gutless compared to my old 6.4

Chrome ash tray with extra LED light!

You'll have to get the delete pipe and a tuner with high sulfer tunes in order to bypass egr, etc...have no idea about MD and their testing. I have over 200k miles on my tuned and deleted 2012 F350 and have an aftermarket turbo. I love it and based on the fact I'm still on the original drivetrain with out failure I'll say that tuning doesn't ruin a truck. I will also say I can see why some would be hesitant to do so during warranty, would suck to have a failure and pay out of pocket, fixing these trucks ain't cheap.

2012 F350 Lariat 4x4 bone stock for now

My '13 F-350 is bone stock & I believe I've pulled my 16,400 pound 5th wheel over every mountain pass in the western United States & haven't had my foot to the floor yet. I am much more interested in reliability , longevity & dependability than power & performance although the power of this truck seems more than adaquate.
Having said all that, if something goes wrong with the truck once it is out of warranty I would consider various deletes & upgrades at that time. 'Not saying that's my plan, but I might check it out.

2013 F-350 Lariat 6.7 L PSD Crew Cab Dually, FX4, white platinum metalic tri-coat with black interior, N-Fab step bars, factory spray-in bedliner and 5th wheel hitch, trailer tow package, integrated brake controller, upfitter switches, Sync with My Ford Touch, memory group, remote start, reverse sensing with rear view camera, nav, satillite radio, Weather Tech floor mats, limited slip diff, moon roof, climate controlled seats, engine block heater and tailgate step.

2014 Lifestyle (formerly Carriage) 5th wheel 38' long with 3 slides & all the goodies.

SOLD: 2005 F-350 Lariat, 6.0 PSD, Torqueshift auto trans, crew cab, SRW, short box, FX4, ESOF, limited slip dif., tow command, upfitter switches, 6 CD changer, Lariat Lux. package, camper package, engine block heater, triple A-pillar gauge set (Autometer) with pyrometer, trans temp & voltmeter, MBRP 4" cat back exhaust w/5" dual wall chrome tip, dark shadow gray/ med. flint interior.
