The 05-10 Chrysler Gas 1r13k does what exactly versus 1r09c? I don't like to put an update unless there is something worth doing so when nothing is broke.
And why would my original tune backed up be 55kb and the perf cai 91 modified be 5kb? I would think they should be similar in size.
Is there an app to open up these tunes on a PC to compare parameters side by side?
