I'm gonna try it without it first but if I need a tuner I will get one. Ive done a little research and like the Bully Dog but is Superchips better? I know this sounds stupid but I can't stand the seat belt chime. I'm in and out of my truck quite frequently and having to put my seat belt on to drive around fields sucks. Is there a way to turn this off without a tuner? I saw it was an option on the bully dog.

 

i have the flowmaster super 40, and my friend with an 08 hemi went to a muffler shop cause he loved the sound of mine to put it on his hemi, but they wouldnt do it they said it didnt have enough air flow or some bullsh!t. but i know of a hemi that has a super 40 on it. anybody know why they wouldnt put it on there?

 

I have a super 40 on my truck. Not a great muffler IMO, as soon as I get some extra cash I am getting a magnaflow. The FM is basically rusted out after about a year and a half.
