DPF Delete only or DPF/Cat Delete ???
I am new to the forum and have just purchased an 08 F-250 crew. I have seen that the best setup is to get rid of the DPF system to gain fuel mileage and a little performance. I was wondering if you guys could steer me in the right direction and help me choose what to get.
When I purchased the truck it came with the SCT tuner in the glovebox(unknown which tunes are loaded on it) and a full 5" Magnaflow straight thru from the downpipe back to include the 6" polished tip. Well this was an issue at the MA state inspection garage because they immediately knew the catalytic converter was gone after seeing the giant exhaust tip and looking underneath. It failed so now I have the stock exhaust back on the truck. MA inspection/emmissions is just like the California limits.....Unfortunately.
I would like to know what I should get to help boost fuel mileage and help my power a bit. Is it better to get a DPF delete only pipe and keep the cat in place or is it better to do the DPF/Cat delete pipe and why?? what are my advantages of doing away with one or both??? I would like to do the delete pipe setup and keep the stock tailpipe setup so it is a little more stealth to the average joe. It will also be easier when it comes time for emmisions testing to swap it back and forth.
What tune setup should I run to get the best possible everyday driving without doing any engine damage or screwing up my nice new truck? The SCT Tuner screen gives the option of (Stock, Trans only, Performance, or Extreme) .
Any and all help would be greatly appreciated with this.
