Hey Scotty, I have a 1997 Pontiac Grand Prix GTP with the 3.8 supercharger. I would like to know if it is safe to use CRC Throttle Body/Air Intake Cleaner to clean the throttle body even though it says not to?

On that I'd remove the throttlebody to clean it to be safe so you don't risk harming the supercharger rotor surfaces.

Yes, try that
