Newb with question about tuning
I recently purchases a 99 WS6 that has some mods. It has long tubes and cam and a few other mods. It was dyno tuned at Race Proven Motorsports (RPM) in Delaware by the previous owner. I would like to purchase my own tuner so I can learn and tweak things as needed. I want to eventually change the heads but that may require a pro tuner at that point.
Do I need the same tuner that RPM used when they tuned it or can I use any of the available tuners?
How do you save the current tune that is in the ECM, so if I mess things up I can get back to the current tune?
Thanks for the help.
