Ok.
I am ready to add another programmer to my truck . I already have a superchip but it doent have a dpf delete and I think I want one. I have already installed the Banks cold air intake as well. So should I spend the big bucks and go for the sparten with thedpf delete or maybe the sct live wire with the dpf delete? Also should I go with 4 inch or 5 inch exhaust? I want a nice rumble but not too load. Oh yeah sorry my truck is the 08 6.4l super duty and I love it.

 

Spartan is hands down the best money you will spend on your truck. As for the exhaust, the only thing you gain going with the 5" is maybe a little more rumble. The 4" is more than enough flow so you won't see an increase in power or MPG with the 5".

 

out of curiousity, did your mpg increase with the superchip? if so how much?

 

gain maybe 2 mpg in the performance mode.
