Looking for Recommendations 
I want to get general tuning done for my Suzuki Swift 2010 model.
Also trying to understand how reliable these service packages are that include:
• Catalytic converter cleaning
• Oxygen sensor cleaning
• Fuel injector cleaning
• Fuel pump cleaning
If anyone has done these services before, please share your experience
Were they worth it, did you notice a difference, and were the mechanics honest?

Thanks in advance!
