I recently bought a srt4 has the turbo toys in dash and was told its the stage 2. How can I find out for sure what it is and also how do I know if any of the controls are properly working when I use them?
If your turbo is stock and you have toys then it's stage 2. You can confirm by checking the part number on the fuel injectors (P4510529) and the MAP sensor (P4510365). If your turbo says MOPAR on the housing, then it's stage 3. Check the Turbo Toys information sheet that's attached on how it should function.
Retro, I found a shitty scanned copy of the stage 2 information sheet also.
