Should a TC3 with a 2-speed be able to beat a stock 4Tec if both are tuned properly? I just got beat by a 4Tec and I am wondering if his car is that fast, or is my car just not tuned properly? I can't imagine a 2 speed making a TC3 go 60+ mph. I believe I may be running rich due to the fact that not only does my car leave a trail of white smoke, it leaves a light spray of oil on the street. Also should I be using foam tires or rubber for better grip on asphault? The stock tires just spin crazily on take off and turns.
