Don't know how the livewire works but can you change the tunes/parameters now that you switched your exhaust??

it's possible but shouldn't be noticable. what are the details on your exhaust. turbo back?

well the sct doesn't have any adjustments for different exhaust. and I haven't ordered any custom tunes because I basically use my truck for towing and I don't need to hot rod it considering all the horror stories about 6.0 head stud issues. so I only use the street tune and tow 65 features that came already programmed when I bought the programmer. the exhaust is a 4 inch turbo back magnaflow that came with the truck when I bought it. I chopped the muffler off and ran the pipe right out in front of the rear tire. but now I am thinking about putting the muffler back on and running the piping back up and over the rear diff and out the back the way it was before. I heard from a friend that the way my exhaust is now is good for towing because of the EGT advantages but sucks for daily driving because you loose some bottom end and gas milage.
