what can i expect
 

Ok,
Here is the deal. I have an f250 with 6.4 and leaning pretty hard at a spartan tune of 275, with CAI and DPF delete. I am going to purchase a MBRP 4" exhuast system.

So what can i expect? Good bad or ????

Thinking about the Snow meth/water stage 2 also

Little help would be good, this is my first ford and first diesel

Thanks
