INTUNE issue!!!! ASAP

[cubaco54]

I have a 2005 Dodge Magnum RT with K&N CAI, throttle body spacer, JBA short headers, magnaflow downpipes with no catalytics, magnaflow catback exhaust, MSD wires and an oil catch can. Tried installing multiple tunes and all of them made my car have a rough idle and run horribly. I then tried to restore my factory settings and the INTUNE gets stuck on "restoring tire size". I tried this multiple times and still doesn't go any further.

Please note I did all updates that the INTUNE required prior to trying any tunes and also completed the PCM calibration update that the INTUNE said to do when I first plugged it into my OBD2 port.

Please advise ASAP!

Its because you have an 05. Disconnect the battery for a few minutes after you install the tune. Reconnect it and all will be good. The 05 MDS system has a tendency to lock up.
