6.4 to 6.7

Hello everyone
I am about to trade in my 2009 Lariat for a 2012 king ranch.
I love my 6.4 but I wanted to move to a king ranch and the egr cooler thing freaked my out. I did a cat dpf delete, cai and 4 filter back on my 6.4 with a Spartan.
I have some questions
1. For those coming from a 6.4, what are your thoughts.
2. Should I reuse the Spartan or are they cracking down on the tuning?
3. It says on the sheet it's a job 1, on a 2012, any problems with them, freaked out with 6.0 and stupid 6.4 issues
4. What kind of mileage with 3.55 rear end?
5. For the 6.7 guys how many miles on your and any problems?
I feel like I betrayed international....but it's so smooth

I've never owned a 6.4 but my dad had one i currently have a 6.7 though and let me tell you it is awesome...I have the 3.55 rear end with the electronic locking rear end and my overall average mileage towing and straight driving is is 17.4...I have about 14500 miles on the truck. My last 5 tanks I have not gotten under 18 MPG I think this is because the engine is getting broken in better. My dads 6.4 for was an awesome truck after he did all the deletes but stock to stock the 6.7 is ten times the truck I can't wait till I get the extra money to delete mine and see what the truck really has in it. The only problem I've had so far is today when i went to but a fuel filter for my truck my local Ford garage wanted 95 bucks for it...but I ended up getting the same filters for 68 at our local Kentucky motors store...Ive seen you can save a lot of money by shopping around and doing your own simple maintenance on these trucks. I hope this helps a little I would definitely recommend this truck and engine to anyone in the market for a diesel truck...I've driven the other brands and also older fords and owned a dodge but this new truck and engine blows them all out of the water...Just wait till you hook the new one to a loaded trailer you wont even remember you have one behind you on a long drive.
