Im looking for a tuner for my 2007 Chrysler 300c, the ones that have cought my eye so far are the diablo intune i2 and i3. If im going to buy one id like to be able to use it on multiple vehicels, so i also need some info on how the licensing works. i found an i2 for $15 that i might bid on if i know i can use it on my car for cheap enough. its set up for a corvette right now so i know id need to purchase a license. How much does the license cost? ive seen about $100 so far. do i purchase a Chrysler license, or is the license vehicle spacific. Can i get brand spacific licences? Also i saw some of the diablo products are not compatable with all wheel drive vehicles, is the i2 compatable? Thank you for any info!
