2009 Challenger SRT8 Six Speed

This is my first time using a tuning product and I was a little confused and concerned about the tool being set to support 5.7 and 6.1 engines. I'm assuming it scanned and recognized the details of my vehicle (6.1, Six Speed, 3.92 gear ratio, 20" tire size, etc) when it backed up the stock tune. The tool has options for changing these and doesn't show the current settings from the canned 93 CAI tune, so it's a sort of leap of faith that this is how it works.

If the tool is "smart" and picks up on these details from the stock tune, it might be worth having this in the FAQ for us new guys just coming up to speed so we don't worry or fidget with settings that are already accounted for. Just offering some "new customer" feedback. Great product by the way!!

The Predator and Trinity use what is called a calibration ID(calid) to identify your vehilce and apply the proper settings.
The parameters should all be in default positions the first time you go into the modify tune section, it will not reflect the proper tire size as we display a default value for that, if you have not changed your tire/wheel size, there is no need to touch it.
