i have an sct chip the the 5 selector switch and for me to tune this chip myself i would have to buy the Racer's Pro Package for 650-700 dollars (tuning software and chip burner) or i could buy the TwEECer RT for about 600 dollars. Wich would be the better way to go ??? Both tell me they can give me my current tune so i'm not starting from scratch. Someone once told me that TwEECer's reset if crossing under high power lines. Wich is better and why???
