vehicle is a 2007 300C SRT8 and it has a procharger on it. Dealership doesn't know much about the car other than the basics.
1. How can I tell what tune the car has?
2. will a installing a diablo tuner mess up the tune currently installed?

Any help would be appreciated. thanks

best way to see what tune is on the car is to find someone who has hptuners to read the tune on the car and compare it to a stock file for that car that you can find on the hptuners website. installing a diablo would definitely be a bad idea unless it was a custom diablo tune for the mods on the car but a regular diablo tune that comes with the hand held tuner would be bad.

Thanks for your help. I was able to research and found out the injectors are 42lbs.

A tune is way more than just the size of the injectors. As said above, the HPTuner is the best, and about the only way to see the tune. Comparing with a stock tune will give you an idea what has been changed. Fuel mixture, ignition timing and spark plug choice/gap are the most critical items to be concerned with when using forced induction.
