Someone recently used my old website (yep, still active I guess after shutting it off 2 years ago) to buy an exhaust kit. I did return the fund since I don't make them anymore. So please, don't go on the website to buy exhausts... but all the links for the different maps are still working.
This might be a stupid question, but is a new exhaust and the airbox mod absolutely required for the Viper RevB map? Also if I am using the speedoDRD will it interfere with the power commander? Also which power commander is compatible with the tune, can I use III, or do I need power commander V?
Edit: After testing, it doesn't appear to absolutely need an exhaust or the airbox mod, but it is possible that adding an exhaust with the airbox mod and timing advance mod would increase power past what Marthy's maps are capable of with stock configuration.
