Last weekend my mechanic wasnt satisfied with my car's performance although i wasnt complaining so much about it. So he decided to do on-road tuning under the not-so-hot afternoon. I was sleepy at that time so i waited at the workshop and waited for the result. When my mechanic came back with the recorded runs on the laptop, my car was running like a turbo charged engine. Heck, i tweaked around with my SAFC and SITC. After few more runs, the car felt better, smoother and no knocks in the cabin.
