FORD 6.7 / Cummins 6.7 /Duramax 6.6
 

all three trucks are extremely nice.

I will be getting a 4 door long bed with and automatic.

I want to know after I delete/ chip, which truck become the fastest 0-60.. and has an auto that can handle a chip and delete kit.

I know they will all pull my trailers with out any problem so I'm not worried about that..


also which is faster stock? beings I will leave it stock for a while that is important as well.

They are all nice, but it hard finding the delete kit for the newer ones because of the government cracking down on the companies making them.
Are you looking for the new ones with def or without def?
