Have you replaced the Xpipe or are you?
Please give some more info on the DSP 91 tune as well. What is it and where do you get it? I know it's a program but is it a hand heled you plug into the ECU? How much was it?
I love this forum! I am learning so much and still waiting for my Express to be built lol.
Other than the muffler, I haven't done anything to the exhaust system. I'm looking at the Y pipe and figure it's days may be numbered, but that is on next summers list of 'possible' mods.
The DSP 91 tune is installed using the DSP (Diablo Sport Predator) tuner. It is a handheld unit that plugs into the diagnostic port, and accesses the PCM from there. I bought mine from a member here, and got a great deal. The 4 sale section is a great place to shop.
For you 2012, there are no tuners available, as Dodge did some nasty encryption to the code starting in 2011, so until someone cracks the encryption, your pretty much SOL.
