I recently bought a 2005 GT and it has quite a few mods done to it.
Cam swap, rear-end, Hurst speed shifter, headers and full exhaust.
I was hoping to grab a tuner and update the settings for the rear-end so I can calibrate the speedometer.
The problem is I don't have the stock tune and I'm not sure if the new programmers are capable of downloading the modified tune so I can back it up in case something was to go awry. Or heck, even if they're capable of downloading a tune that doesn't match the device.
It's definitely not worth bricking the car to fix the speedometer.
What are my options?
