Extracting more power and torque from any vehicle will put more stress on components, the more you make, the more stress you effectively generate, however it is all relative. If you had 2 identical vehicles, one driven conservatively and one driven hard every day, the one being driven hard would naturally wear out components faster as you are using all of its power and torque. Our Caddy is a 2018 2.0 tdi 102hp and has spent the last 31,000 miles tuned with no issues and needing nothing more than maintenance work. I hope this helps 🙂
