2013/14 vs 2015/16

Going to buy a used f350 srw diesel - plan to have a delete kit done right away - I have read that the 2015/16 had some parts updated, seems like maybe turbo was one of those, over the 2014 and back models -

2 questions for you guys -

1) Should I even consider anything older than 2015 ?

2) If the answer to #1 was yes, what issues need to be updated or modified to increase reliability.

Thank you in advance for taking time to share your knowledge on this thread and help me out -

Absolutely no issues with the 2013/14 model years. For 2015/16 model years, the horsepower/torque numbers increased to 440/860 over the 2011 to 2014 model years' 400/800 numbers. The difference being, no more wastegate for the bigger turbo, an updated high pressure fuel system, the FRT sensor and low fuel pressure sender are now one sensor and only the primary cooling system cools the EGR cooler for the 2015/16 model years.

Just have a look at the engine hour count on the truck you are considering purchasing, and compare it to the actual driven mileage to get an idea of how the truck was used by its previous owner.

By the way, I'm a Ford dealership technician who owns a 2016 F-250 which I've owned since new, so I can vouch for its reliability.

Either year models would serve you well.

If deleting is on your agenda, the 15-16 trucks have more power potential with the bigger turbo and pump. Only downside to them is the transmission isnít as stout as the 6Rs in the 2011-2014 trucks. They removed some clutches, so if your tuning isnít great and you are rough on it, issues come pretty quick.

Either way you go, check the site for potential failures common to all 11 - 16s. If you're doing a delete you might go for a cold side intercooler pipe replacement at the same time. Rudy's seems to be the most popular because of its price. Rudy's and Mishimoto's seem to be identical with Rudy's costing less.

It’s a very well documented fact that the 2015+ guys have more trans issues tuned than the 2011-2014 guys do when compared tune only. Yes, the 2015+ trucks make right at 100 more HP than the 2011-14 trucks, but there are numerous guys beating on 11-14 stock 6Rs over the 700HP with very great results versus the 2015+ guys at that power level with upgraded chargers and fuel.

I would be most concerned with the deal on the truck. The 15-16 supposedly have a weaker tranny and a have been thought to spin the crank gear. Those issues lean twards the extreme tunes driven by extreme drivers. I bought a 16 in 16 for the simple fact i could not find 13+ really any cheaper then new. Most of the 3yr or less old trucks had 30k+ miles and the price difference wasnt enought to justify it. I love my truck its been great but if i had it to do over i probably would have gone xlt to avoid the large screen not that ive had a single issue out of it but im betting it will be expensive if i do. I also am at just over 25k miles and i can tell you i hate the def, regens and the emission stuff. My truck just started setting a def heater code. I will most likely be deleted by the end of the year

Sounds like the real question is what color, trim, and gearing are you wanting. You can still be picky and likely find what you are wanting searching across all years.
